Auxentius, Junior — originally Mercurinus, a Scythian, and a disciple of Ulfilas, or Wulfila, of whose life and death he wrote an account that the Arian bishop, Maximinus, included (383) in a work directed against St. Ambrose and the Synod of Aquitesa, 381. This favourite of Justina was the anti-bishop set up in Milan by the Arians on the occasion of the election of Ambrose. He challenged the latter in 386 to a public dispute in which the judges were to be the court favourites of the Arian empress; he also demanded for the Arians the use of the Basilica Portiana. The refusal to surrender this church brought about a siege of the edifice, in which Ambrose and a multitude of his faithful Milanese had shut themselves up. The empress eventually abandoned her favourite and made peace with Ambrose. (Baunard, Saint Ambroise, Paris, 1872, 332-348; Hefele, History of the Councils, I).
