Zosimus (d. Dec 26, 418 CE) was bishop of Rome from March 417 to December 418 CE. He succeeded Innocent I (402–417 CE). In his brief episcopate, Zosimus seems to undone much of his predecessor’s legacy and to have antagonized many as he followed a self-aggrandizing path asserting unprecedented claims for his authority as Roman bishop. Liber pontificalis records that he was Greek and that his father was named Abraham. This may suggest some Jewish heritage.
