LEX ROMANA CANONICE COMPTA. - A collection of canonical and Roman texts contained in the codex Paris. 12448 (10th century). It is composed of decretals, conciliar canons, texts from the Registrum of Gregory I and from the Commonitorium of this Pope. The Roman texts included are drawn from Justinian’s *Institutiones*, the *Codex*, and the *Epitome Iuliani*, along with the oldest scholia to Julian.
It includes the *sanctio pragmatica pro petitione Vigilii*. There is also a section derived from the *Capitulare italicum* of Lothar of 825. The appended Roman texts bear mention of their provenance; for the *Codex*, the formula “ex libro codicum” is used. The collection is furnished with glosses. The chapters deal successively with clerics (1–168), laity (169–308), and penal discipline in ecclesiastical matters (309–24). The purpose of the work is revealed by the incipit of the collection, which states: «Incipiunt cum sententiis suis Capitula Romanae legis ad canones pertinentia».
As regards both its content and origin, the collection is widely held to be from Ravenna and dated to the 9th century, also in view of its relation to the *Collectio Anselmo dicata*; but recently the hypothesis has been advanced that the place of composition was Pavia or some other city in Lombardy.
