After the king's death Nordin shared in the general disgrace of the Gustavians and lived in retirement at the little town of Hernesand, where he held the post of lector at the gymnasium.
But it is evident that he must have written his work De Eruditione Filiorum Regalium (where he styles himself as "Vincentius Belvacensis, de ordine praedicatorum, qualiscumque lector in monasterio de Regali Monte") after this date and yet before January 1260, the approximate date of his Tractatus Consolatorius.
About 1270 he returned to Oxford and taught there, being elected in 1275 provincial minister of the Franciscans in England, but he was soon afterwards called to Rome as lector sacri palatii, or theological lecturer in the schools of the papal palace.
His work was continued in the 5th century by Philostorgius, Socrates, Sozomen and Theodoret, and in later centuries by Theodorus Lector, Evagrius, Theophanes and others.
For some time before 341 he worked as a lector (reader of the Scriptures), probably among his own countrymen in Constantinople, or among those attached as foederati to the Imperial armies in Asia Minor.
Entering the Dominican order in 1254, he became lector, prior of the convent, provincial of his order in Lombardy, and in 1296 its general.
His propensity to the marvellous was at an early period exposed in the following verses by Leland: "Hectoris historici tot quot mendacia scripsit Si vis ut numerem, lector amice, tibi, Me jubeas etiam fluctus numerare marinos Et liquidi stellas connumerare poli."
His father, an Irish clergyman, the Fearleighlinn, or lector, at the university, was said to have been of noble family.
