Thessalonicae item natalis beati Aristarchi, qui discipulus et comes individuus fuit sancti Pauli Apostoli, de quo ipse Paulus ad Colossenses scribit: « Salutat vos Aristarchus, concaptivus meus ». Is, ab eodem Apostolo Episcopus Thessalonicensium ordinatus, tandem, post longos agones, sub Nerone, coronatus a Christo, quievit.
