Cicero,
On Divination 2.24.51-52 (tr. W.A. Falconer):
But indeed, that was quite a clever remark which Cato made many years ago: "I wonder," said he, "that a soothsayer doesn't laugh when he sees another soothsayer." For how many things predicted by them really come true?
vetus autem illud Catonis admodum scitum est, qui mirari se aiebat quod non rideret haruspex haruspicem cum vidisset. quota enim quaeque res evenit praedicta ab istis?
