Irpex
Irpex, HIRPEX, or URPEX (perhaps from ἅρπαξ), a harrow with iron teeth, used to clear the fields of weeds and to level and break down the soil, drawn by oxen (Cato, Cat. Agr. 10.; Varr. L. L. 5.136; P. Diac. p. 105 M.; Servius on Verg. G. 1.95). It was probably simpler than our harrow, since Varro calls it regula, i.e. a straight piece of wood. The word is a rare one, and the bush--harrow seems to have been more in use (Verg. l.c.; CRATES).
