Born of Osiris is an American deathcore band, formed in 2003 in Chicago. The group underwent several name changes, including Diminished (2003–2004), Your Heart Engraved (2004–2006), and Rosecrance (2006–2007), before finally settling on Born of Osiris in 2007, basing the name off the Egyptian deity Osiris, and the tale of his son Horus.
