Abu-Nuwas (756-815) was a famous Arabic/Persian poet. He even appears several times in The Book of One Thousand and One Nights. He wrote this letter:
I die of love for him, perfect in every way!
Lost in the strains of wafting music,
my eyes are fixed upon his delightful body,
and I do not wonder at his beauty.
His waist is a sapling,
his face a moon,
and loveliness rolls off his rosy cheek.
I die of love for you, but keep this secret:
The tie that binds us
is an unbreakable rope!
