Collectio ‘concilii secundi Arelatensis’
From Clavis Canonum
The Collectio ‘concilii secundi Arelatensis’, not to be confused with the Collectio Arelatensis, is a fifth-century collection of 56 conciliar canons attributed wrongly to a council of Arles. The collection is lost, but its contents can be reconstructed from later collections drawing on it.
