Wait, Pierre. Before going further I’d like to elaborate on my post of yesterday.
You presented two depictions: a fresco from a church in Bulgaria (ca. 1258) and an illumination from an Armenian manuscript (ca.1250) located in Jerusalem.
I produced two textiles with motifs very close to the paintings. Pope Boniface VIII was elected in 1294 and died in 1303 so his chasuble should have made (in Sicily or Cyprus) in that period. The “samite” fabric of Spain instead is at least a century older than the illumination. It is probably of Muslim manufacture.
Looking for rugs in Armenian miniatures I found this one:
The Armenian Archbishop Jean of Cilicia, 1287.
That should be a rug. Nothing useful, though, apart for a detail that has nothing to do with rugs: it’s the classical Chinese dragon-with-flamed-pearl on the Archbishop garment that is quite surprising.
A Chinese textile used for an Armenian Archbishop's clothes.
This reminds us once more how textiles and motifs - especially the luxury ones - traveled freely and were used even in spite of their different religious origin.

Filiberto
