So about the months with R in them, how did this start? MARK KURLANSKY (Author): Nice to talk to you, Liane. It's called The Big Oyster: History on the Half Shell, and he's in the studios of member station KUOW in Seattle. Kurlansky, who has written bestselling books on cod and salt, has now written one on that tasty bivalve. However, Mark Kurlansky writes that this is an ancient and somewhat mythological belief, but with an element of truth.

As far back as 1599, William Butler, a contemporary of Shakespeare, wrote, It is unreasonable and unwholesome in all months that have not R in their name to eat oysters. The month of April is the last one before September which contains the letter R.
