Following Seneca’s quote of the use of “tribade,” in the 1st and 2nd centuries CE, uses of the term in Latin are closely connected with astrological literature, and appear in very similar formulas (some clearly deriving from each other or from a common original), such that we can derive additional context from similar formulas that use other language, as well as context from Greek astrological literature that uses the Greek form of the word. Boehringer provides a chronology of the exact sources, with their dates and the word forms used in them.
