One of several depictions of Antinous, the Emperor Hadrian's partner/companion, in the Vatican Museums. His face can be seen on quite a few statues/busts in museums across Europe.
Here he is depicted as Osiris-Antinous.
Gregorian Egyptian Museum, Vatican City; July 2019

I actually saw this piece some years ago when it was on loan to the British Museum in London.
