In my opinion, the article overstates the lack of a vocabulary for women to express same-sex desire though it points out tendency for records to be filtered through hostile lenses. As a symbol of the problems with the evidence, it looks at an image of two women kissing while dancing from the Roman de la Rose as symbolic of desire being evident and overt without being clearly categorized or named.
