Here is a companion picture from Yoma, fol. 84, col. 1.--"Rabbi
Yochanan was suffering from scurvy, and he applied to a Gentile
woman, who prepared a remedy for the fifth and then the sixth

following apologue: 'I once went to a place called Kushta, where
the people never swerve from the truth, and where (as a reward
for their integrity) they do not die until old age; and there I
married and settled down, and had two sons born unto me. One day
as my wife was sitting and combing her hair, a woman who dwelt
close by came to the door and asked to see her. Thinking that it
was a breach of etiquette (that any one should see her at her
toilet), I said she was not in. Soon after this my two children
