Plate from Tabriz Museum

Salve,
my friend Patryk Skupniewicz 'published' his paper on the Tabriz Museum Battle Dish, allegedly a Sassanian workmanship.
 I am giving this link here, aside from  my own obvious interest and fine merits of this work, because of a recent publication on the arts of Hellenized East where plenty of published artwork allegedly from the Parthian and Sassanian periods of Persian history can be seen that is very much unlike the Persian art we have been used to see  etc. Are those objects most amazing lost arts of the ancient Persians or very beautifully made 'fakes'?
The paper can be read and /or downloaded here.
 The plate in question - with some detail

The photos above come from the Persian Horseback Archery Association.   
Enjoy
