The Old Woman and the Cask

The Fables of Phædrus
An Old Woman espied a Cask, which had been drained to the dregs, lying on the ground, and which still spread forth from its ennobled shell a delightful smell of the Falernian lees. After she had greedily snuffed it up her nostrils with all her might; “O delicious fragrance,” said she, “how good I should say were your former contents, when the remains of them are such!”
What this refers to let him say who knows me.
