Answer:
Saphho was a resident of the island of Lesbos, and she is where we get the modern term "lesbian." However, Sappho was married to a man, and wrote love poetry about him, but she also wrote love poems and erotic poems about other women. She was most likely attracted to both men and women, making her roughly bisexual in today's terms. The terms "lesbian" and "bisexual" did not exist in antiquity, however, so Sappho could not have identified as either of them. Sappho was not a lesbian, as she was attracted to both men and women, and the word "lesbian" was not invented while she was alive.
