Crambe bis posita, mors

By frequent repetition, even the most pleasant and agreeable story tires, and at length nauseates, as do also the most favourite viands. The particular plant called Crambe by the ancients is not now known. It was thought to have the power of preventing the inebriating effects of wine, and hence we are told, a portion of it, previously baked, was usually taken by the Ægyptians, and some other nations, before sitting down to their tables, that they might indulge more freely in drinking; but twice baked, or too often taken, it excited nausea and disgust, whence the proverb.
«Occidit miseros crambe repetita magistros». -JUVENAL.
To hear the same lesson, so oft repeated, is the death of us poor masters.
