Another Medieval Mystery Sword?

[Lee]

Here is what has been another mystery sword to me defying confident classification; I am beginning to suspect that it might also be Couronian.

Overall length is 26.6 inches in the present state with the blade remains being 21.25 inches of that and the weight being 531 grams.

The upper guard and five-lobed pommel are separate hollow bronze castings, now loose. The end of the tang does come through the top of the pommel where the tang has been peened to retain it and there is a dominant central lobe. A 'mismatched' iron lower guard curves towards the blade. If the corrosion is hiding a fuller, then it must be quite shallow and the blade seems to be somewhat lenticular in cross section.

Again, your observations are welcomed!

Thanks again for sharing, it is a interesting puzzle to ponder... I have more doubts about this one however. I cannot find any examples of Curonian swords with opposingly curved upper and lower guards, whereas this is quite typical of some late Anglo-Saxon or Anglo-Scandinavian swords (most classifiable under Wheeler's type VI). The lobes on Curonian pommels are generally horizontal or nearly so at the base - this seems to be consistent across every photographed and illustrated example in the articles at our disposal.

Below are links to a few stray pommel caps found in England that show the five-lobed form, curved at the base to fit the curved guards. These are the most similar in overall appearance that I could find, there is a great variety of other lobed shapes in the database.

Reventlov, I think you have made some very good points. These bronze pommel variants of Wheeler VI do indeed resemble the sword presently under consideration.

They vary a bit from my expectations for Petersen type L hilts, as those that I have knowingly encountered have relied on rivets from the upper guard to attach the (often lost) pommel.

As the British Museum kindly allows distribution of the images in their Portable Antiquities Scheme under a Creative Commons BY licence, I have attached reduced size versions of them below for convenience.

Reventlov's recognition above of pommel features in common with documented English isolated finds may very well have initiated recognition of a new localized British variant of Viking Age sword.

This type appears to be characterized by:

• A hollow pommel of cast copper alloy...
• with five lobes, the central being dominant...
• that is secured by an exposed peened tang at the top of the central lobe.
• An upper guard (pommel bar) curving away from the grip...
• and an oppositely but similarly curved cross guard.

On the basis of the curved guards, this type most closely resembles Peterson's type L or Z while the dominant central lobe recalls type S.

Tomáš Vlasatý has prepared an excellent detailed analysis of this sword comparing it with similar examples and also reviewing where it stands within several classification systems.

This is a fascinating analysis of this sword as pointed out, and while I am totally a novice at this field of study in swords of this antiquity, my interest was piqued in some of the elements of this one.

I was wondering about the character of the lobed pommel, in this case the five lobes, and why that design was chosen or what it might represent. Although the complex classification systems developed by Petersen, Wheeler et al are used for typology study and are useful in estimating period and probable origin, I hoped to find more historically.

According to Hilda Ellis-Davidson in "The Sword in Anglo Saxon England" (162. p.54) she offers an interesting suggestion apparently posed by Guy Laking in 1920 . In this, claimed by him to come from an 'eminent' authority, the lobes signified an amulet tied to a sword pommel, as was sometimes described in literary sources. However she suggested that such practice would have been 'clumsy' so unlikely.....further being inclined to think the lobed pommel evolved from animal head decoration on pommels.

On p.55 (op. cit.) the author notes that Wheeler (1927) describes the curved pommel base with lobes enclosed in the curve with ends turning upward, the guard also curved downward with acute or gentle curve. Wheeler uses the term 'Wallingford type' for location of find of one with acute curve (though tri lobed) but later found it was from Abingdon.

Another of these was found at Wensely churchyard with five lobes, and Wheeler suggested that this class of hilt 'originated in England' due to the Anglo Saxon work on the Abigdon find.


Further description goes to lobes within a less acute curve to Baltic regions and possibly a Danish fashion?


While what I have added here is admittedly rendered from the eyes of an intrigued novice in this field, I enjoyed using this great example to search through some references I have to learn more.

Thank you for sharing this wonderful example.

Hi Lee,
Very interesting, thanks for sharing this! I think Tomáš addresses the nuances of the various typologies very well. It has been clear to me for a while that the definition of Petersen's type L has been interpreted over-broadly to include quite a disparate variety of swords, and classification into more specific sub-types is definitely appropriate. I can only wish I had written this analysis myself... if my earlier observations were of any inspiration at all, that would still be very gratifying!

A minor point of correction through clarification. It would not be a "copper alloy" but a "high-copper alloy". I know it's barely relevant and doesn't seem all that important but there is a difference. Which is useful to recognize.

Copper alloys are those which contain any amount of copper but for which copper is not necessarily the primary material (such as pewter or monel). These are often also called by their principle component. Such as monel being a nickle alloy. But not always. As in with the case of pewter being categorized as a copper alloy even though a true pewter is primarily tin (true pewters are basically a reverse bronze).

High-copper alloys (such as brass or bronze) contain mostly copper with some secondary and often tertiary material (especially in older specimens the tertiary material is often an undesirable impurity that is tolerated for lack of knowledge on how to eliminate it, such as arsenic, phosphorous, or sulfur).

It's a cladistic thing in the classification of alloyed metal products (i.e. All high-copper alloys are copper alloys; Not all copper alloys are high-copper alloys).

Additionally I would say that the over all red-sh patina with gray to white oxidization in the low points, that are somewhat green or green sheen in certain spots and from different angles, makes it fairly safe to call this a true bronze (if we're interested in being more specific than asserting it as a copper/high-copper alloy). While both zinc and tin may oxidize as white. Only tin also phases more into gray and sulfates as a blueish-green. Which can produce the white from some angles and slightly greenish tinge from others. As can be seen in the OP's set of images.

This indicates the alloy being majorly comprised of copper with a low percentage by weight of tin. I would also say that the second images provided of a very similar pommel have corrosion characteristics of arsenic-copper. It may still be a true bronze. But the source for the copper or in that case may have had a fair amount of arsenic contamination. Back then they wouldn't have been all that good at working such impurities out.

To be clear that doesn't mean that these can't be the same typo-logically. Just that there was a bad luck of the draw with one in smelting. But these are somewhat different alloys. Though likely made via the same process. Back then one just couldn't control as tightly as we can today even following the exact same prescription.

I mention this bit because people seem to have a tendency to think that the differences in patina between presumed same materials are down to preservation conditions. But unless we're contrasting say an ocean wreck recovery vs. a shallow dirt-dug recovery, this really is rarely the case. At least in coloration, same materials tend to corrode the same. It takes fairly drastically different conditions to get fairly drastically different patinas.

Helleri, I plan on renting a portable XRF (X-Ray Fluorescence) unit in the near future to go through the entire collection. I will follow up with the elemental composition in this thread when I have that data. I expect you will be proven correct - it looks and feels like bronze.
