The date of the council is given in two different ways - the first is a date in the Spanish era which began in 38 BC, the second is a date according to the years of the reign of Theoderic. In the case of the council of Lerida the dates do not agree - year 584 in the Spanish era is AD 546 and the 15th year of the reign of Theoderic is AD 525. The other provincial council held in Valencia was also dated to the 15th year of Theoderic, but the date in the Spanish era there is 587 (so AD 549). The scholars assumed that the name of the ruler was corrupt in the manuscript tradition and they proposed that we should read Theudis. King Theudis began to reign in AD 531, so the 15th year of his reign would be AD 546 (with references to the early modern commentators Hefele 1895: 132; Orlandis, Ramos-Lissón 1986: 124-131).
