My flatmate said, “he turned a ring into a penis” and I knew I needed to find this book. Amores by Ovid is fascinating yet hilarious, particularly Elegy XV which is a love letter to a mistress…
“To touch her hand thou wilt the pleasure have;
I now must envy what myself I gave.
O! would a Proteus or a Circe change
Me to thy form, that I like thee might range !
Then would I wish thee with her breasts to play,
And her left hand beneath her robes to stray.
Tho' straight she thought me, I will then appear”
