Note 1638 — BOOK III.
Lewis Evans translation
Quartarius, "quia partem quartam questûs capiebant." "The mule-drivers were so called, because they received one fourth of the hire." Of course, as the animals were not their own, they were not very careful how they drove them; and hence might run foul of the cippi, which were either tomb-stones by the side of the road, or stones set to mark the boundaries of land. Cf. Juv., Sat. i., 171. Pers., i., 37. Hor., i., Sat. viii., 12.
