Towards the middle of the fifth century, perhaps earlier, there appeared a Latin version of the aforesaid canons of Nicæa, Ancyra, Neo-Cæsarea and Gangra, to which were added a little later those of Antioch, Laodicæa and Constantinople; the canons of Sardica were inserted about the same time after those of Gangra. Bickell considers it possible that this version was made in Northern Africa, while Walter inclines to Spain; it is now generally believed that the version was made in Italy. It was long believed, however, that it came from Spain, hence the name of "Hispana" or "Isidoriana", the latter term derived from its insertion in the collection attributed to St. Isidore of Seville (see below, Spanish Collections), in which it was edited, of course according to the text followed by the Spanish compiler.
