Note 1482 — PERSIUS.

Baro is no doubt the true reading, and not varo, which some derive from varum, "an unfashioned stake" (of which vallum is the diminutive), "a log;" and hence applied to a stupid person. Baro is, as the old Scholiast tells us rightly for once, the Gallic term for a soldier's slave, his Calo; and, like Calo, became a term of reproach and contumely. It afterward was used, like homo (whence homagium, "homage"), to mean the king's "man," or vassal; and hence its use in mediæval days as an heraldic title. Compare the Norman-French terms Escuyer, Valvasseur.
