The piece depicted has only a brief description in the Museum's catalogue and I am not sure where the dating information came from but it is very interesting if true.
"Several iron plates, often very slender, roughly circular or polygonal (4.4 to 7.4 cm in size) with a strong central rivet holding a small counterplate, may have come from a broigne (Fig. 149-9 to 21). The spacing between the two plates corresponds in any case to the section of a thick leather (0.5 to 0.6 cm)"
Source: Colletiere de Charavines p. 216 from Musee Archeologique du Lac Paradru. Translated by Google Translate. I have no more bibliographic information than this as I'm working from a incomplete scan of the catalogue.
Attached are small images of one of the plates, in all probability excavated from the mud of Lake Paradru.
Has anyone got any information that would lend credibility to the claim that this is from an 11th century coat of plates? I know it is a century earlier than the conventional beginning of the use of CoP. I think the most likely answer is that it is a misdating, a misinterpretation of an artefact (it doesn't have four rivets and could be something else), a mistranslation or some other misunderstanding but I'm curious as to whether others have encountered this particular artefact. If it is truly what is being speculated on then it is a very exciting find.
