"Juan de Biclaro, también conocido como Juan de Bíclaro, Juan de Bíclara, Juan Biclarense o Juan Biclaro (en latín Iohannes Biclarensis), fue un clérigo católico y cronista de origen godo. Nació aproximadamente en el año 540 (siglo VI) en Scallabis, entonces en la provincia de Lusitania, hoy Santarém (Portugal). En el año 559, siendo muy joven, marchó a Constantinopla y regresó al Reino visigodo en 576. El rey Leovigildo intentó sin éxito convencerle para que se convirtiera al arrianismo, pero al no ceder a las presiones del monarca, fue desterrado a Barcino (la actual Barcelona) en 577. No pudo abandonar la zona hasta unos diez años después, posiblemente debido a la llamada del propio Leovigildo y del obispo godo Masona hacia 585 o 586. Después de 589 fundó el monasterio de Biclarum, cuyo emplazamiento se ha situado recientemente en la población de Cabacés (Tarragona). Durante años varios historiadores situaron este cenobio en Vallclara, cerca de Montblanch, donde a finales del siglo XII existió un monasterio, probablemente restaurado. Aun así, investigaciones recientes apuntan a la posibilidad de que este monasterio se ubicase en la población también tarraconense de Cabacés, llamada Vallclara durante la Reconquista, y donde existen unos vestigios arqueológicos que apuntan poderosamente a la presencia en la población de un edificio religioso del siglo VI. Antes de 592 fue consagrado obispo de Gerunda (Gerona). Como obispo de esta sede firmó las actas del Sínodo Provincial de Zaragoza de 592; también asistió al Concilio de Toledo de 597, al II de Barcelona de 599, y seguramente también al de Egara (la actual Tarrasa) de 614. Escribió un Chronicon sobre los años 567 al 589 que es una importante fuente para la época y una continuación de la crónica escrita por Víctor de Tunnuna. Su muerte se fecha hacia el año 621."
"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." A more likely reason for John's detention was his lengthy stay at Constantinople, with the possibility that he might be a spy for the Byzantine governors in the far south of Iberia. An enforced stay in Barcelona certainly put him out of possible treasonous contact with the Byzantines. John does imply that Arians received favorable treatment under Leovigild, once, in connection with the Arian council convened by Leovigild in 580, where Catholic bishops were ignored. After Leovigild's death in 586, John was released and founded a Benedictine monastery at Biclaro (the exact site is undetermined), where he presided as abbot and finished his Chronicle (in 590), before he was appointed Catholic Bishop of Girona under the new episcopal government. John took part in the synods of Zaragoza (592), of Barcelona (599), and of Egara (Municipium Flavium Egara) (614). His chronicle, which is a continuation (from 567) of the chronicle of Victor of Tunnuna, in Africa (Chronicon continuans Victorem Tunnunensem), reaches to the year 590. It was printed as early as 1600 and has provided the most complete and reliable authority on Leovigild's stormy reign, and on the Visigothic conversion from Arianism to Catholicism, in an impartial narrative. Three other chronicles cover parts of the Visigothic rule of Hispania: the bishop Hydatius, bishop Isidore of Seville, both of the doctrinally unified Catholic Visigothic establishment, and the fragmentary but apparently secular Chronicle of Zaragoza. A bishop of Girona known as Johannes Gerundensis ("John of Girona") seems to have been a successor of the chronicler, though some have identified him with the chronicler."
