Why does heraldry fail?

[Diane]

R.Sale,
I did look into your idea.
If you were positing some connection to the Genoese  I'd think it not unreasonable. The period when members of the Fieschi were elected Pope is also not unreasonable if you posit the present ms gained from earlier sources. But these are positions which have to be argued by more substantial reference to historical documents, art history, palaeography and so on.

At present the argument has some fairly obvious flaws: the pattern you call 'papelonny' occurs in many other media, for example, and it is plainly wrong to call a 3rdC mosaic, or an Islamic ceramic pattern  "papelonny" when in the first case European heraldry had yet to be invented, and in the second  the maker is highly unlikely to have intended any reference to European coats of arms.

So where's the evidence which requires us to say that the pattern on that barrel has any reference to European heraldry, either?

If people don't respond to your idea, it's very likely because you don't explain how you first came to have it - whether it just occurred to you one day, or whether it was something which you concluded after a study of certain historical documents, secondary sources, comparative imagery and so on.

If, among documents of the Fieschi popes, or of the Fieschi family in general, you were to find some very similar imagery to some in the Vms, or some of the same unusual glyphs, that would certainly add weight to your idea.
