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).
