Leading his army back up the Euphrates, south of Circesium Philip erected a cenotaph in honor of Gordian III, but his ashes were sent ahead to Rome, where he arranged for Gordian III's deification. Whilst in Antioch, he left his brother Priscus as extraordinary ruler of the Eastern provinces, with the title of "rector Orientis". Moving westward, he gave his brother-in-law Severianus control of the provinces of Moesia and Macedonia. He eventually arrived in Rome in the late summer of 244, where he was confirmed "Augustus". Before the end of the year, he nominated his young son "Caesar" and heir, his wife, Otacilia Severa, was named Augusta, and he also deified his father Marinus, even though the latter had never been emperor. While in Rome, Philip also claimed an official victory over the Persians with the titles of "Parthicus Adiabenicus", "Persicus Maximus" and "Parthicus Maximus".
