Maitland Quarto Manuscript
Unsurprisingly, the material here is (with one possible exception?) filtered through male authors. We have literary tales of same-sex desire under the cover of gender disguise. There are medicalized case studies that--to a modern reader--sound more like intersex and transgender individuals, but those concepts were inextricably tangled with understandings of lesbianism at that time. And we have two poems, placed in the voice of a female narrator who is trying to come to terms with desiring another woman (though one is known to have been written by a man).
Renaissance philosophy tackled the question of friendship: who is an appropriate friend, what behavior should a friend exhibit, what is the relationship between the love of friends and sexual desire? Given the times, the majority of texts addressing this topic were concerned with friendships between men, though a nod was often given to Sappho as a proponent of female friendships, or to the possibility of “Platonic love” between women, which is given explicit license in the Symposium as well as by Renaissance writers commenting on it, as Agnolo Firenzuola did.
