He was known as the patron of the cities of Ghent and Macerata. The Paternoster (Our Father prayer) of St. Julian can be found as early as 1353 in Boccaccio's "Decameron", and is still passed on by word of mouth throughout some places in Italy. The account is included the 13th-century "Leggenda Aurea" of Genoan Giacomo da Varazze, a Dominican priest. Beautiful stained glass depicting St. Julian by an unknown artist in the Cathedral of Chartres also dates back to the 13th century. Early fresco paintings of him are found in the Cathedral of Trento (14th century) and the Palazzo Comunale di Assisi.
