Islamic coins as jewellery: finds from Viking England


It is well-known that the Vikings had extensive and deep contacts with the Islamic world. In the archaeological record, this is manifest most strikingly in the tens of thousands of Arabic silver coins (dirhams) that survive in Viking-Age hoards, settlements and graves across the Scandinavian world. The number of extant coins indicates the huge importance of Eastern trade routes via Russia, particularly during the tenth century. In this century (mostly in its first half), it is estimated that 125 million whole dirhams reached Northern Europe from Central Asia. 125 million!

For the most part, dirhams were treated as high-quality pieces of silver, to be used within the Scandinavian metal-weight economy. But a significant minority of them were used more creatively, and turned into ornaments to be worn on necklaces, primarily as part of female dress. This phenomenon has long been attested within Scandinavia. But a few recent finds raise the possibility that the Scandinavian fashion for dirham ornaments was also transferred to Viking-settled England.

One such dirham-pendant recently came to light in Lincolnshire, part of the Danelaw area of Scandinavian settlement. It is a Samanid coin, minted in 905/6, so will have reached England in the 910s at the earliest. In addition to being pierced for suspension, it is gilded on both sides. A diagonal area without gilding may have once held a pin-fitting, suggesting further re-use as a brooch.

Normally, dirhams just have a single piercing, suggesting they hung from a necklace. This is also supported by their position in graves, around the neck or upper chest of the deceased. But multiple, opposing piercings are seen on coins strung on pendant chains. These are more elaborate necklaces featuring multiple coins, usually separated by rings or multiple silver chains, that are found mainly in Finland, Estonia and southern Scandinavia in the later part of the Viking Age. The one below comes from a hoard deposited after c. 1120 AD in Blekinge, southern Sweden. It has 10 coin-pendants, including Islamic issues and coins from Western European and Byzantium.

A dirham with multiple piercings is also known from North Yorkshire. The holes probably result from riveted attachment loops, now detached. The dirham may have once been suspended taut on a pendant chain - possibly in England, but perhaps more likely in the Baltic/ Scandinavia. But the fact that it was found singly in the Danelaw suggests it was eventually lost during an economic transaction. This coin, then, had multiple 'lives', as a coin, ornament and, finally, a piece of bullion currency.

Dirhams carry several lines of Arabic script, including the name and date of the ruling caliph, the location and year of the minting and the name of the mint master. They also carry quotations from the Quran. Was this text comprehensible to the wearers of the dirham pendants? Almost certainly not. 

But this is not to say that the text itself was meaningless. Indeed, the position of the piercings on Islamic dirhams shows that they are usually orientated so that the lines of text are positioned either vertically or horizontally i.e. symmetrically, ensuring that the script was clearly visible (as on the example above). This suggests that dirham-pendants were seen as more than just decorative items. They were also symbolic - perhaps signalling the owner's access to high-quality silver coins from the East, or simply to exotic goods, brought from afar. As the pendant chain above demonstrates, dirhams can appear next to other types of coins on the same necklace/ chain, including Western European coins displaying crosses. Such necklaces seem to be making a statement about the wearer's diverse and far-reaching cultural contacts, as well as silver wealth.

Did Viking women settle in England?

This is a contentious and long-standing question for students of the Viking Age. And it’s one bound up in the wider debate about the scale of western Viking settlement more broadly. Those who argue that the Vikings who settled in England in the late ninth and tenth century (following decades of raiding) were a numerically small warrior-elite see the Scandinavian settlement as a largely masculine affair.  But those who (like me - see my recent debate paper in Antiquity or a popular article here) argue that the settlement was large-scale and involved whole families migrating across the North Sea maintain that Scandinavian women were integral to the establishment of new farmsteads.

In the past, the small number of known Scandinavian female burials in England has given fuel to the argument that few Viking women settled in England.  But over the last two decades, a fresh source of data has emerged giving an entirely different perspective. New discoveries of female Scandinavian jewellery, made by metal-detecting, offer the first tangible evidence for a substantial contribution of Scandinavian women to the Viking settlements.

A Scandinavian snake pendant (Borre style) found in Norfolk. This pendant would have hung from a woman's necklace. The snake may have acted like an amulet, protecting the wearer from misfortune. Image copyright PAS. 

To date, over 150 female jewellery items from Scandinavia have been discovered in England – almost exclusively in areas known to have been settled by the Vikings (East Anglia, Lincolnshire and Yorkshire). These items are brooches and pendants, often decorated in the popular Viking art styles of the time: Borre and Jellinge. They are identical to jewellery items found in Scandinavia, especially in southern Scandinavia (modern-day Denmark). And there are lots of different types – trefoil brooches, with three ‘arms’, small domed disc brooches decorated with animal faces and contorted bodies, different styles of pendant, some in the form of snakes (see above), others disc-shaped……the list goes on and on. Most are made of copper or lead alloys and are not especially high-status - more Zara than Prada. In archaeological terms, 150 is a lot. And we have to remember that these are only the items that were lost at the time (and not recovered), survived in the soil for over 1000 years, found by a detectorist, and reported to the relevant bodies. 150 is likely just a tiny fraction of the actual number of brooches circulating at the time.

While the pendants were worn suspended from necklaces, the brooches would have been pinned to the chest, with larger brooches securing an outer cloak. Anglo-Saxon women also wore brooches, but the types I’m talking about look very different – in their shape, decoration and even their pin fittings. They would have stuck out a mile if worn in rural Norfolk circa 895.

But do these jewellery items necessarily imply the presence of Scandinavian women? Couldn't they simply have been imported trade goods, or represent local products that were worn by Anglo-Saxon women in imitation of Scandinavian fashions? In my opinion, no. The material is far too diverse to represent the average stock of a merchant, while technical features such as the pin arrangement on the reverse of the brooch, and even the metal alloy, indicates that they were not made according to Anglo-Saxon methods. Moreover, the distribution of this material is rural and very widespread, as if these items had been lost by women on or near their farms. If items were being imported and sold on, we would expect clustering in towns.


Pin-fittings on the reverse of brooches, including the middle loop with the ring attached, show that these brooches were manufactured in line with Scandinavian traditions. This brooch has been gilded to look like gold, but it was made of copper-alloy.
The jewellery offers a tangible marker of a female Viking presence in England. But other evidence also points to Scandinavian women living in England. Scandinavian feminine names are preserved in minor place-names, referring to fields, streets and rivers (names that are likely to have been coined by local Norse-speaking farming populations). Hildr in Hilderholm (Lincolnshire), Gerđr in Gerdeswelle (Norfolk), and, interestingly, from the perspective of Scandinavian women in towns, Guđrún in Goodramgate (York), are all examples. Place-names incorporating women’s names and ending in ‘by’ (meaning village/ settlement) and ‘thorpe’ (meaning secondary settlement) suggest independent landholding by women bearing Scandinavian names. Gunnhildr in Gunby (Yorkshire), Ragnhildr in Raventhorpe (Lincolnshire and Yorkshire), and Ingiríđr in Ingerthorpe (Yorkshire), are all examples.

More broadly, it is likely that women who shared a common, Scandinavian culture with male settlers had a decisive role in preserving that culture in a new setting. In historical migration contexts, it is typically women, more than men, who maintain international kinship connections, store knowledge about personal histories, preserve social customs and adjust cultural practices. Critically, the mother’s cultural background usually filters down to the next generation more strongly than the father’s. In the context of the Viking settlement of England, we know that Old Norse survived in some parts of England into the tenth and eleventh century. A prerequisite for this must have been the presence of Norse-speaking women, using Scandinavian speech in the home and passing their language on to their children (The alternative scenario: that Scandinavian male settlers married local, English-speaking women, who then learned Old Norse and raised their children in that language, or bilingually, is far less likely).

The evidence for a female contribution to the Viking settlement of England continues to grow, as new finds are made year on year. Perhaps it’s time we re-cast our image of the Vikings in England, to include women (and children) alongside men.

The dual-currency economy of the Danelaw


Cowrie shell money issued in late 18th century West Africa.

The co-existence of two or more distinct currencies is a common phenomenon throughout history. In ancient Greece, silver bullion circulated alongside coin. In medieval Scandinavia, weighed silver, cattle and grain were common forms of payment, even within the same transaction. French francs and local cowry shell money were concurrent currencies in nineteenth-century West Africa – one of many examples where ‘state’ or ‘colonial’ moneys were introduced to societies with pre-existing, ‘local’ or ‘indigenous’ currencies. 

As I argue in a new Antiquity paper, a dual-currency economy also operated in the Danelaw region of eastern England, where the Vikings settled, following a period of raiding activity, in the late ninth century. Here, a wealth of new archaeological evidence indicates that the Vikings introduced a bullion currency based on weighed and tested precious metal. Over the last few years, I’ve documented evidence for hundreds of single finds of Scandinavian silver ingots, chopped up bits of ring and foreign coin, as well as standardised weights, all presumably lost by accident in areas where they were in frequent use. Yet it’s clear that this bullion economy coincided with a second silver currency, namely coinage, some of it minted by the Vikings themselves. Critically, bullion and coin circulated at the same time and in the same areas for 60 years or so (roughly 870-930 AD): a good two generations by the standards of the day.


In the Danelaw area of northern and eastern England, bullion and coin co-existed in a dual-currency economy
How did this work in practice? Was the use of coin and bullion split down ethnic or cultural lines (those using bullion and coin having little to do with each other)? Or did Scandinavian settlers use coin in addition to bullion, perhaps using different media for different monetary purposes?  One interesting pattern is that locally minted coins -the official Danelaw currency- are rarely treated as bullion in Viking-settled areas.  They are rarely tested or cut, although they could of course have been weighed – a treatment that would leave no physical trace. This suggests to me that the Viking settlers used coinage, alongside bullion, perhaps preserving coin for use in towns where exchange was closely monitored and bullion finds rare. The purse of a Scandinavian trader likely contained bullion as well as local coin, the duality of payment media ensuring that she was prepared for all exchange eventualities.

Why preserve bullion, when coinage was widely available? Underlying this question is the assumption that coinage is somehow ‘better’ than other forms of money: more sophisticated than crude weighed silver currency because it (unlike bullion) requires authentication and regulation by a state, and more convenient because it reduces the number of ‘transaction costs’.

But there were many advantages in using bullion.  It was better suited than coin for large transactions (no need to count out 100 pennies when a single ingot would do the job). It was also easier to exchange with international trade partners, since raw silver, unlike coinage, was acceptable across national frontiers. Silver bullion was easy to test for quality (via nicking), whereas contemporary coins could be a bit dodgy, with frequently low silver contents, running the risk that they might not be accepted by your trading partner. Whereas coins were periodically called in for reminting (and thus, one’s coin stock was effectively taxed), silver bullion was not regulated, and in this way retained its value over time. It is also possible that the performance of a bullion transaction was tied to Scandinavian identity in England. Maintaining a bullion economy may have been a means by which Viking settlers marked themselves out as different from the local Anglo-Saxons.

Tribute or wages? The fascinating coins of the Watlington hoard - part 2.


The Watlington hoard contains nearly 200 silver coins, the vast majority of them minted by the Anglo-Saxon kings Alfred ('the Great') of Wessex and Ceolwulf II of Mercia. These coins would have been standard currency in their area of jurisdiction during the 870s, so how did so many  end up in the coffers of one (or more) Vikings? 

One distinct possibility is that the coins represent ransom payment given by the Anglo-Saxons to the Vikings to, essentially, get them to go away.  This practice is well documented in the late tenth century, when the Anglo-Saxon king Æthelred, nicknamed Æthelred Unræd ie. the Unready (ruled 978-1013 and 1014-1016 AD) made a policy of paying out huge sums of tribute payments to would-be Viking attackers. As a result, thousands of Æthelred’s coins have been found in Scandinavia (see pictures below). This tactic may explain why Æthelred the Unready was so named: translated from the Old English, his name means “noble counsel, bad-counsel” (or, as one eminent Anglo-Saxonist put it “noble counsel, my foot!").

I excavated this coin of Æthelred on a Viking-age farmstead at Slite, Gotland, Sweden (waaay back in 2005). Thousands of Aethelred coins are found in Scandinavia: testimony to the Anglo-Saxon practice of paying off would-be Viking attackers. (my photo, my hand)

But although often associated with Æthelred, ransom payments are also hinted at in the ninth century. In a typically English indirect style, the Anglo-Saxon Chronicle describes how the Anglo-Saxons ‘made peace’ with Viking forces on various occasions during the military campaigns of the 870s and 880s, thereby averting battle. On such occasions, Viking forces probably demanded, and received, cash in hand. This is certainly suggested by other sources. A document from 872 describes how the bishop of Worcester, one Wærferth, resorted to selling land for gold because of the ‘very pressing affliction and immense tribute of the barbarians’. The Vikings pursued a similar policy of extracting cash bribes during their raids on the Carolingian Empire and in Continental sources there is no such beating around the bush. In 866, Charles (the Bald) ‘made peace with those Northmen at the price of 4,000 lbs of silver, according to their scales’ (the Vikings were clearly dealing with silver by weight). He later ‘collected the amount he had agreed to pay those Northmen, both in silver and in wine’. 

The Watlington hoard was hidden immediately following an intense period of Viking military activity in southwest England. Alfred had ‘made peace’ with the Vikings at Wareham in 875, at Exeter shortly thereafter, and at Chippenham in 878. Alfred defeated the Vikings, under their leader Guthrum, at Edington in the same year. Some weeks later, Guthrum was a guest at Alfred’s court; here, Alfred sponsored Guthrum's baptism and ‘greatly honoured him and his companions with riches’. The coins in the Watlington hoard may have been acquired by the Vikings on one or any of these occasions, with the Anglo-Saxon Chronicle – a pro-Wessex/ Alfred account – understandably not wanting to detail the cash transfer.  Certainly, the coins have a narrow date range and this is a good indication that they were gathered together shortly before being deposited. 

Silver coin of Ceolwulf II of Mercia, who is recorded only fleetingly in contemporary annals, and who disappeared around the same time the Watlington hoard was buried (c. 879/80).

But, beyond being a ransom payment, there is another, intriguing, possibility. This period also saw Alfred, ruler of Wessex, take over the neighboring kingdom of Mercia, and in c 879 AD, the Mercian ruler Ceolwulf II vanishes without trace (see blog below).  Could the coins have been acquired by the Vikings not as tribute, but as payment by Alfred for military services against Ceolwulf?  This is pure speculation, and would involve an otherwise undocumented alliance between Alfred and the Vikings. Still, the hoard was deposited at exactly the same time Ceolwulf drops out of historical sight.

Rewriting history: the fascinating coins of the Watlington hoard - part 1

In 2015 an important Viking silver/ gold hoard was discovered near Watlington, Oxfordshire. The hoard appears to have been in Viking hands when it was buried in c. 879/80 AD. It contains a characteristically Scandinavian mix of coins, ingots and both complete and hacked jewellery. But its standout feature is its c. 200 silver coins. All but a handful were minted by the Anglo-Saxon kings Alfred (the Great) of Wessex (ruled 871-899) and his much less well-known contemporary Ceolwulf II of Mercia (ruled c. 874-879). Surviving coins of the 870s are rare. As explained in this new mini-book, the hoard casts vital new light on one of the most formative periods of medieval British history.


The Watlington hoard included a typically-Viking mix of coins, ingots, arm-rings and hack-silver, in addition to a tiny piece of hack-gold. (Copyright Ashmolean Museum)
Ceolwulf II is barely mentioned in the main documentary source for the period, the Anglo-Saxon Chronicle. This pro-Wessex source, first written down in c. 892, describes Ceolwulf as a ‘foolish king’s thegn’: a puppet ruler put in place by the Vikings to rule over western Mercia on their behalf in the late 870s, while they were busy attempting to subdue other Anglo-Saxon kingdoms.
But the coins tell a different story. In the Watlington hoard, coins issued by both Alfred and Ceolwulf (individually, rather than jointly) share the same design, and in some cases the same moneyer and mint place, suggesting some kind of monetary alliance on a grand scale: only possible if Alfred accepted the legitimacy of Ceolwulf and was willing to partner up with him in public. One of these is called the ‘Two Emperors type” because of the image of – you guessed it – two emperors on the reverse of the coin. Only two were known before this new discovery, with the current total now 15. Clearly, the coins were far more numerous than previously thought. The silver content of the coinage also seems to have uniformly increased around this time, further suggesting joint action.

The winged figure above might be an angel, or a figure of Victory. If the latter, it's possible that the coinage was issued to celebrate the success of an otherwise unknown military coalition against the Vikings. (Copyright Ashmolean Museum)
Despite this monetary alliance, the relationship between Alfred and Ceolwulf quickly soured as Alfred moved to annex the kingdom of Mercia in around 880, and the shadowy Ceolwulf disappears from the historical record altogether (perhaps having been invited for a refreshing cliff-top walk). The fact that the coin types represented within the hoard have so far proved rare may indicate that Alfred deliberately melted them down following his takeover of Mercia, perhaps wanting to erase all reminders of Ceolwulf and their (now-embarrassing) former relationship. Indeed, Alfred began to issue a new coin type (the ‘Two-Line type', so called because…….yes, it has two lines of writing on it) at exactly this time.
A 'Two-Line type' coin of Alfred, found in Wiltshire. The two lines on the reverse of the coin read 'WLF RED' ie. Wilfred, the moneyer who produced the coin. (Copyright PAS). 
One of these new issues is included in the hoard - but just one. It seems that the Watlington hoard was assembled and deposited at a key moment of transition, when the Alfred-Ceolwulf coins were being melted down, but before Alfred had time to produce lots of his new 'Two-Line type'. Were it not for this hoard, we might well have consigned Ceolwulf to the margins of history. But the coins suggest that Ceolwulf was a legitimate ruler whilst painting Alfred as a shrewd manipulator of the facts.

An unexpected absence: Anglo-Saxon silver in Viking hoards

The recent excavation of a Carolingian silver cup found in 2014 as part of the Galloway hoard revealed a number of extraordinary objects. Among them was a series of large Anglo-Saxon silver disc brooches, in styles that date them to the ninth century.  Such objects, worn by the Anglo-Saxon elite (possibly in pairs) seem like an obvious choice for inclusion in a Viking hoard.  Yet rarely are Anglo-Saxon silver objects found in such contexts.

Anglo-Saxon silver items such as brooches, mounts and strap-ends, ought to have been highly prized by the Vikings. Surviving ninth-century silver is usually good quality (over 90% precious metal), an important feature for the Vikings who carefully screened for debased metal. It is also highly decorative, frequently depicting lively, semi-naturalistic animals in the so-called Trewhiddle style (as seen on the brooch below). These are given added emphasis by niello inlay, a black copper/ silver sulphide, which provides a striking contrast with a silver background.  In Viking hands, such silver could be worn as high-status dress items, or broken up as a form of hack-silver currency.

A fragmented Anglo-Saxon silver brooch with niello inlay, depicting 9th century animal ornament.
The brooch formed part of an Anglo-Saxon hoard from Norfolk.  We know from the date of coins found with the brooch that it was buried in or around 869 AD, the year the Viking Great Army invaded East Anglia. The brooch is 95% silver. (Copyright Portable Antiquities Scheme) 
But the Anglo-Saxon brooches from the Galloway hoard are unique in their context, and other Anglo-Saxon items in Viking hoards notably few and far between. The largest Viking hoard on record from Britain, from Cuerdale, Lancashire, contains over 1,100 silver artefacts, but just a handful of Anglo-Saxon pieces, including fragments from a disc brooch, a brooch pin, and fragments of a strap-end and mount.  Anglo-Saxon silver jewellery is also rare within Scandinavia, suggesting that the Vikings only occasionally transported it home. Rare examples include two broken and cut Anglo-Saxon disc brooches from Sweden (from the Sturkö and Igelösa hoards), which likely functioned as bullion currency.

Why this unexpected absence? The Galloway hoard demonstrates that Anglo-Saxon silver objects must have passed through Viking hands, and Anglo-Saxon silver coins are a common component of hoards from Britain. Clearly, it is not a question about access to silver. 

The answer may lie in the form of the silver itself. Large disc brooches were not part of Scandinavian dress, while the distinctive animal and vegetal decoration of precious metalwork set it apart from indigenous Viking styles.  I think it’s likely that Anglo-Saxon silver objects were routinely melted down into forms that the Vikings found more ‘acceptable’, such as ingots and rings.  Silver is these forms fit more readily with the Viking aesthetic and could be easily assimilated into their currency systems.

In principle, then, the Scandinavian bullion economy made use of all silver, regardless of its form. But in reality, it preferenced silver in a limited range of homegrown and instantly recognisable shapes.

Where were dirhams fragmented?

A good way of learning about the uses of silver within a bullion economy is to measure the extent of silver fragmentation. Whereas the frequent occurrence of highly fragmented silver suggests that silver actively circulated as money (that is, it often changed hands in commercial settings), the dominance of large, complete silver items suggests that silver was mainly stored as wealth.

One source of Viking silver that is often found in a fragmentary condition is Arabic dirhams – the critical source of silver fuelling the Viking bullion economy. Patterns of dirham fragmentation have the potential to reveal important insights into the local use of silver.  But, first, we have to establish where dirham fragmentation took place.

A big question is: were dirhams broken up near their source, in the Caliphate, or following their import into the Baltic and Scandinavian lands? The answer is, most likely, in both areas.  From c. 850 AD Near Eastern mints stopped producing coins to fixed weight standards, and a couple of decades later, broken dirhams start to appear in local hoards. Such fragments were probably required to ‘top up’ weighed payments to the required sum. Some hoards contain upwards of 40% fragments, suggesting that these pieces formed an important part of local monetary circulation. So some dirhams arriving in Scandinavia after c. 850 will have been fragmented already.

But it’s also clear that dirhams were further fragmented within Scandinavia. This is shown by the fact that the degree of dirham fragmentation across Scandinavia varies region by region. Writing in the 1980s, the Swedish numismatist Brita Malmer found that just 35% of hoarded dirhams from the Swedish island of Gotland were fragmented, compared to c. 66% of dirhams from the Swedish mainland provinces of Södermanland and Småland and 91% of dirhams from Östergötland. What’s more, the fragments from Östergötland were much more finely divided than those on Gotland. 

These patterns may partly reflect differences in local hoarding practices rather than the overall balance of fragmentary and whole dirhams in the local currency, but it seems clear that some dirham fragmentation took place locally.  In addition, whereas dirham fragments from Near Eastern hoards are usually roughly broken, many fragmented dirhams found within Scandinavia have been cut to sharp edges, probably with a chisel, and this provides a strong clue that division took place locally. Some dirhams found in Scandinavia have both broken and cut sides, suggesting at least two different locations of fragmentation (for examples from Kaupang, Norway, see the chapter by Mark Blackburn in this publication).
A complete dirham from Northamptonshire. Half of dirhams recorded singly in England are complete. (Image PAS)


Exactly where dirhams found in England were cut is difficult to say, and the answer will no doubt vary from coin to coin. Dirhams travelling as far west as England probably changed hands many times along their journey from the Caliphate, and thus stood a high chance of being cut at some point. Among the c. 60 single finds of dirhams I’ve recorded from England, half are whole (as the example shown above) and half are cut. The cut coins have an average weight of just 0.59g: less than a quarter of a complete coin (weighing c. 3g).


A very thin dirham fragment from Torksey, Lincolnshire, weighing just 0.38 grams. The edges are roughly broken, rather than cut, perhaps suggesting that it was fragmented in the caliphate. (Image PAS)




Interestingly, dirhams from Viking military camp sites in England are even more finely divided. At Torksey, Lincolnshire, occupied by the Viking Great Army in 872/3, over 90 dirhams have been found, but none are complete – they are all fragments with an average weight of just 0.44g: less than 1/6th of a complete coin. Notably, even ‘young’ dirhams that had only recently been minted, are very fragmentary.  Assuming that extremely fragmented dirhams were unlikely to have travelled over long distances in a short amount of time (simply because they would likely be lost in the process), this suggests that these coins were at least partly fragmented at Torksey. However, the sliver of a dirham shown above is roughly broken, rather than cut.  It may have been entirely fragmented in the Near East. 

In sum, the evidence suggests that at least the final stages of dirham fragmentation were carried out locally, rather than from a central source. Patterns of dirham fragmentation do, then, seem to be a good guide to regional bullion needs and economic structures.

The art of the silversmith: stamped decoration on Viking silver

Stamped decoration is ubiquitous on Viking silver. This blog takes a quick look at how it was executed.

Within Scandinavia, the two most common shapes for stamps to take were ring-stamps and triangles, often containing 1 or 3 pellets. Often, two triangles were placed end-on-end creating an hourglass shape.

Such simple shapes were relatively easy to produce. In most cases, a punch was applied to the surface of the object soon after casting. To avoid a double impression, the punch had to be made in a single blow. Actual examples of punches used to create the ornament are rare, but one example comes from a late Viking-Age tool chest found at Mästermyr on Gotland. This is essentially a square iron rod, which originally had an hourglass shape on the striking face (it’s now very worn). A lead pad from the same tool chest seems to have been a testing piece for this stamp and others: it is covered on both sides with stamped hourglasses and rings.

(my photo, taken at the Fitzwilliam Museum)
But although the stamps themselves are rare, there are a few examples of other trial pieces, always made of lead. Three come from the Viking winter camp of Torksey, Lincolnshire, which the Vikings occupied in 872/3, at the height of their raiding activity in Britain. One of these, pictured to the right, has about twenty punches of a triangle with three dots – a form of decoration that could have been applied to Scandinavian neck-, arm- or finger-rings. When not busy taking over Anglo-Saxon kingdoms, it seems the Viking army was producing decorated silver ornaments (among other items). 

Despite the practice that the trial pieces imply, surviving ornaments show that the application of stamps was not an exact science – stamps were not always evenly applied, and some even contain cracks (see blog post below). This is the case with some unusual trefoil-shaped stamps on a silver arm-ring from a Viking-Age hoard from Yorkshire, which I studied at the Yorkshire Museum. The first stamps were applied in the middle of the ring, and are intact, but as the silversmith moved towards the outer edges of the ring, a crack appeared in the punch. This is clearly visible where the lozenge ornament has split, especially on the upper level of the ring.

Interestingly, it wasn’t always necessary to punch the silver after casting. Sometimes, the ornament could be stamped into a beeswax model, and that model used to create a clay mould from which silver objects could be cast. This is clearly demonstrated by a terrific find from the harbour site of Fröjel, Gotland: it’s a Viking-Age clay mould which preserves stamped hourglass decoration, neatly picked out in the drawing (see here for other examples). This mould would have been used to cast decorated silver arm-rings.

An illustrated database of stamps - building on James Graham-Campbell's recent work in this book - would be of great help in establishing workshop traditions and links between different objects.
