Charlton T. Lewis, Charles Short, A Latin Dictionary

I. A stone curb round the mouth of a well: puteal, περιστόμιον φρέατος, Gloss. Philox.: “putealia sigillata duo,” Cic. Att. 1, 10, 3; Dig. 19, 1, 14.—

II. Transf., a similar curb placed round any spot. Thus, at Rome, the Puteal, erected in the Comitium, to commemorate the cutting of a whetstone with a razor by the augur Attus Navius, near the Arcus Fabianus. It was subsequently restored by Scribonius Libo, and was called also Puteal Libonis. Money matters were here transacted. According to others, the Puteal of Libo was different from that of Attus Navius: “impositum,” Cic. Div. 1, 17, 33; id. Sest. 8, 18; Ov. R. Am. 561: “Libonis,” Hor. Ep. 1, 19, 8; id. S. 2, 6, 35; Pers. 4, 49.
