There were five known "magistri" in the history of the province, though this certainly does not represent the whole. Two are passingly mentioned by Isidore as successive governors in the time of Suinthila, but he omits their names. The first known governor, Comenciolus (possibly Comentiolus), repaired the gates of Cartagena in lieu of the "barbarians" (i.e. the Visigoths) and left an inscription (dated 1 September 589) in the city which survives to this day. It is in Latin and may reflect the continued use of Latin as the administrative language of the province. (It does not, however, imply that Cartagena was the capital of Spania.) Around 600 there was a governor named Comitiolus who bore the rank of "gloriosus", the highest rank after that of emperor. The patrician and "magister" Caesarius made a peace treaty with Sisebut in 614 and conferred with the emperor Heraclius, who was more concerned with matters in Mesopotamia.
