known only from coins, on which we find Cn. Lucretius Trio and L. Lucretius Trio. The specimen annexed has on the obverse the head of the Sun, and on the reverse the Moon surrounded by the seven Triones, or the constellation of the Great Bear. (See Dict. of Antiq. p. 147, 2d ed.) These devices, like many in modern heraldry, are a kind of punning on the name. The Sun and Moon give the greatest light (luc-em), and thus have reference to the gentile name Lucretius ; while the seven Triones are an evident allusion to the surname. (Eckhel, vol. v. p. 239.)
