Parallel - Philosopher's Toothache

Shakespeare:

"For there was never yet philosopher
That could endure the toothache patiently,"
   Much Ado About Nothing 5.1.35-6

Bacon: "It is more than a philosopher morally can digest; ...I esteem it like the pulling out of an aching tooth, which i remember when I was a child and had little philosophy, I was glad when it was done."
   Letter to the Earl of Essex

Comment: The impatience of a philosopher with toothache sounds as though it may have had some classical origin, but editors do not mention any.
