The Chronicle of Alfonso III names "Ervig" as the son of "Ardabastus…from Greece" & his wife. His birth date is estimated from his parents´ assumed marriage date range, working back from the tight birth date range assigned to his daughter Cixilo. He was brought up at the court of King Recesvinto, where he used the title "comes".
After deposing King Wamba in 680, he was elected to succeed as ERVIGIO King of the Visigoths. The Chronica Regum Visigotthorum records that “Ervigius” succeeded “Id Oct 719” and was anointed “XII Kal Nov”. The Continuator of Isidor's Historia Gothorum, Wandalorum, Sueborum records the accession of "Ervigius" and his reign of 7 years. In light of the dubious circumstances of his accession, he married his daughter to his most powerful opponent whom he nominated as his successor, by-passing his own sons. The sons of King Ervigio must have been minors at the time if the chronology of events shown above is correct. In 681, he revised and enlarged the Liber iudiciorum compiled by his predecessor King Recesvinto.
The Chronicle of Alfonso III records that Ervigio "died a natural death in Toledo" having ruled six years and four months. The Chronica Regum Visigotthorum records that “Ervigius” reigned for seven years and 25 days, and died “XVII Kal Dec”. 1
