Matricula
Matricula, a Latin word meaning a register, has several meanings in Christian antiquity. The word is applied first to the catalogue or roll of the clergy of a particular church; thus clerici immatriculati denoted the clergy entitled to maintenance from the resources of the church to which they were attached. Allusions to matricula in this sense are found in the second and third canons of the Council of Agde and in canon 13 of the Council of Orléans (both of the sixth century).
