Lanser is one of the most significant voices in the study of lesbian themes in the Renaissance and early modern period, so it's not at all surprising that she does an excellent job at surveying the literature of the period. I'm a smidge less convinced by her framing discussion, suggesting that the significance of Queen Elizabeth I of England's extended reign as a woman, and as an unmarried woman at that, created a special context for disrupting concepts of gender and increasing discourse around female homoeroticism.
