I think the greatest Persian Poetess was Mahasti Ganjavi!
Mahasati was born at the end of XIth century in Ganja in Azerbaijan, received perfect education, closely acquainted with the Eastern literature and music. The most productive period of creation she spent in palace of Sultan Mahmud Seljuq and his uncle Sanjar Seljuq's palace.
She was a famous rubai writer not only in her epoch, but much more later. The love plot holds the main place in her creations. The rubais are marked out by their wordliness, humanism, epicurism and optimism. Mahasati ganjavi describes love as a fragile natural feeling which makes a man's fame higher. The poetess protested against religious prejudices, hypocricy, conservatism and protected a man's moral freedom. Her poems reflected the people's, especially women's, romantic dreams of a free and happy life.

An turk pesar ke man nadidam sirash
That turkish boy who I couldn't see him enough
Bashad ke zebar bashad o basham zirash
I wish he lies on top of me and I find myself under him
Han ey pesareh khatib ta solh konim
O homosexual Boy, Come to make peace with each other
To ba koonash besazo man ba kirash
You can enjoy with his ass and I with his Penis
