The Construction of Homosexuality

It is a very interesting and readable book. However, there're some incorrect quotes or sources. E.G. p.215 note 174, He cited one old (19 th century) book about Messalina. But as far as I know, her lesbianismus was not written in any classical texts. I couldn't find her same-sex passion either in Tacitus, Juvenalis, Suetonius or in Dion Cassios. The author himself should have read original Greek & Latin texts. Even I an ignorant Japanese did try to read them to find a written proof. And I hope some erudite persons will kindly teach me the authority of her sapphism.
