Sirius Black’s tattoos are ones that he etched himself in Azkaban prison. The three tattoos are a Disillusionment Charm over a map of the wizarding village of Hogsmeade, a Death Eater symbol, and a Dark Mark with a three-headed dog symbolizing Death Eater allegiance. The Disillusionment Charm tattooed over a map of Hogsmeade demonstrates Sirius’ strong emotional connection to his hometown, while the Death Eater symbol indicates his previous involvement with Voldemort’s forces. The Dark Mark may be a reminder of the fateful night that put Sirius in jail, when Peter Pettigrew betrayed Harry’s parents to Voldemort and Sirius’ best friend, James Potter, died. The three-headed dog symbolizing death may also reflect Sirius’ belief in justice and the importance of standing up against evil.
