Varus
a cognomen in many Roman gentes, was indicative, like many other Roman cognomens, of a bodily defect or peculiarity; such as
Capilo, Naso, Paetus, Strabo, Scaurus, &c.
Varus signified a person who had his legs bent inwards (
varum distortis cruribus, Hor.
Sat. 1.3. 47), and was opposed to
Valgus, which signified a person having his legs turned outwards.
