Though the pose of the figures does not resemble the famous Critius and Nesiotes sculpture , the iconography is similar . When I saw the image of an older bearded man and his younger beardless lover stab a rich man in formal robes it seemed the most obvious attribution . In the vase image there is no suggestion of anything mythical , legendary or ritualistic ,so it definitely looks like a contemporary murder .
As I recall the story it wasn’t as noble as the Athenians would like to portray it . Firstly It wasn’t an act of selfless freedom fighters but homosexual jealousy , secondly they killed the wrong man and thirdly did not free the Athenians from the tyranny and may even have made it worse until it was overthrown 3 years later . I may be wrong though , I cant remember where I read about this .
The ‘Copenhagen painter’ is presumably named from a work in the Copenhagen Museum . There seems to be dispute as to the identities of individual vase painters , according to my book on Athenian Red Figure Vases he is linked with the Syriskos painter , they may have been related or belonged to the same workshop .That is about all it says .
