Aesop

“ Then the Debtor fetched a Sow—the only one he had—and took her to market to offer her for sale. It happened that his creditor was there too. Presently a buyer came along and asked if the Sow produced good litters. “Yes,” said the Debtor, “very fine ones; and the remarkable thing is that she produces females at the Mysteries and males at the Panathenea.” (Festivals these were: and the Athenians always sacrifice a sow at one, and a boar at the other; while at the Dionysia they sacrifice a kid.) ”
