In the document approving his commentary on the Sentences, dated 25 May 1333, in Assisi, he is referred to as minister of the province of Aragon. He likely completed his studies in Paris, as suggested by the Explicit of the second book of the Sentences by Friar Francisci Rubei, reported by Friar G. de Rubione, Paris, in a manuscript once held in the Library of the Twelve Apostles in Rome. Another report also indicates the time of his stay in Paris: Explicit reportatio of the fourth book of the Sentences under Master Francischo de Marchia... made by Friar G. de R. in the year of Our Lord 1323 (cod. Chig. B. VII. 113; cod. 53 of the metropolitan church of Prague). It is believed that he was among the immediate disciples of G. Duns Scotus, though no certain proof can be adduced. His commentary on the Sentences, which alludes to other writings of his, such as the Quodlibeta (now lost), was published in Paris in two volumes between 1517 and 1518.
