hi! I accidentally found the persian miniature of the cute boy with long hair that I was talking about. It's from the safavid era, circa 1640

and by the way, the character on the cup reminded me of this persian miniature! (as far as I remember, the thumbnail depicts a guy🤔)

"They shaved his head
To clothe him in ugliness
Out of jealousy and fear
Of his beauty.
They erased the night
And left him in dawn."

Yusuf ibn Harun al-Ramadi
