Regum et imperatorum apophthegmata

Cotys was once presented with a leopard, and he presented the donor with a lion in return. He was by nature very irascible and prone to punish severely any lapses in service. On a time when a friend from abroad brought him some vessels of earthenwrare, very fragile and delicate, wrought with figures in relief in a realistic and highly artistic manner, he gave presents to the friend, but broke all the vessels in pieces, so that I, as he said, may not in anger punish too severely those that break them.
