I put your letter under my left breast --
They say that's nearest the heart
At last, weary, I tried to get to sleep
But love that has been wakened knows no night...
I lay asleep -- no, sleepless -- because the page you wrote
Though lying on my breast, has set my womb on fire.
-- Constance of Angers (a nun) to Baudri of Borgueil (a monk who some theorize was gay)
