forgery

I've found a website that discusses the image of Orpheus crucified. It refers to an article which was published in Aγγελος as early as 1926 and which asserts that the seal is fake. This judgement was made on the basis of the iconography. Interestingly, one of the key points is that the 'sagging' figure (with bent arms and legs) is characteristically medieval and not attested in late antique images of the crucifixion. The page is here:
