This chapter considers how English dictionaries made sense of sexuality beyond modern English society. It begins with the early modern assumption that a nation’s character was commensurate with its language, and that the moderate nature of England’s language and culture entailed that any ‘excess’ found in either must be the result of foreign influence. The chapter examines how sodomy and buggery, along with the semantic field of pederasty, were positioned by etymological, general, and hard-word dictionaries as ethically and ethnically remote, vices practised in the Mediterranean by ancient heathens or modern heretics. These xenophobic associations remained in dictionaries into the nineteenth century. Conversely, lexicographers’ retellings of classical myths of same-sex love—male and female—reveal sites of tension between the moderns’ veneration of Greek and Roman literature and their rejection of its pagan sensuality. The life of Sappho in particular provoked sharp disagreements over what her moral character had been, and what could or should be said about it, in a range of dictionary genres: hard-word, general, classical, and biographical.
