Stories from The Decameron of Boccaccio, edited by Colin Bennett (oversized HC, 1980, $3.50, which is 1/3 the internet price.)
Well, if this not a find:
"The Decameron was Giovanni Boccaccio's greatest work and is probably the best known of all classics of erotic literature. It was started after the Black Death struck Florence in 1347-9 and it is against this sombre background that the stories are set. Ten young people agree to leave the plague-filled city and seek refuge together in the countryside. In the heat of the afternoons they sit together telling stories to pass the time. Surrounded as they have been by sickness and death, strict morals seem unimportant and the storytellers freely discuss subjects they would normally have blushed to mention in mixed company."
BEWARE: Do not read these stories when you are in a library, without expecting everyone to turn to you and say, "Shush...." when you laugh too loudly. (I learned this the hard way!)
Look for this in the classics section. Avail. 1/25.
