John of Biclaro

John of Biclaro, Biclar, or Biclarum (circa 540 - after 621), also Iohannes Biclarensis, was a Visigoth chronicler, born in Lusitania, in the city of Scallabis (modern Santarém in Portugal), who must have been from a Catholic family, to judge from his name. He was also bishop of Girona.

He was educated at Constantinople, where he devoted between seven and seventeen years to the study of Latin and Greek. When he returned to his homeland, he was imprisoned for several years in Barcelona. Isidore of Seville ascribes this to his refusal to join the Arian Church of the Visigothic realm in Hispania.

Modern historians note that other contemporary Iberian sources, including John's own Chronicle do not attest a Visigothic campaign of persecution of Catholics until the revolt of Hermenegild divided Visigothic loyalties. The Visigothic persecutions of dissenters and Jews may be a more recent Catholic myth. Indeed, John wrote that, in 578, "Leovigild had peace to reside with his own people."
