The so-called Second Council of Arles is in fact a collection of canons from several councils, namely the First Council of Arles in 314, the First Council of Nicea in 325, the First Council of Orange in 441, and the Council of Vaison 442. Therefore, the terminus post quem of the collection must be 442 and the terminus ante quem probably 506, the date of the Council of Agde, whose acts are not included in the collection. This collection also includes some canons of unknown origin, which are the only ones included in the database.
