Satyrus had in his earlier years, as well as St. Ambrose, practised as an advocate, and held office. But when his brother was appointed Bishop of Milan, Satyrus at once gave up his appointment, and devoted his life to managing St. Ambrose’s secular affairs, that nothing might distract him from his episcopal duties. After however, a few short years of devotion to this task, he succumbed to a severe illness October 17, a.d. 379.
