Marcus Volusius was proscribed by the second triumvirate while holding the office of aedile. According to Appian he borrowed a robe and a dog's-head mask from a friend who was a priest of Isis [more likely Anubis], and thus disguised he made his way to safety - Appian's Roman History IV, trans. H. White (Loeb, 1955), 220-1 (Book IV c.6). The same story is told, at greater length but with less detail, by Valerius Maximus in his Facta et dicta memorabilia Book VII c.3.
