He at first joined the convent of the Reformed Franciscans at the church of S. Maria di Ara Coeli, and taught at Genoa and Turin.
Another of his possible works was a treatise entitled Oratio doctissima et efficacissima ad Franciscum Gonzagam totius ordinis ministrum generalem pro pace et disciplina regulari Magni Conventus Parisiensis instituenda, Paris, 1582.
Luke Wadding calls him, in his supplementary volume, 'Thomas Bourchier Gallice, Lacton vero Anglice, et Latinis Lanius, vel Lanio, Italis autem Beccaro' (an alternative form of Beccajo), and elsewhere exarkinson, the author of 'Collectanea Anglo-Minoritica,' consider them two distinct pepresses himself convinced of the identity of Lancton and Bourchier.
Another treatise by Bourchier, De judicio religiosorum, in quo demonstratur quod a sæcularibus judicari non debeant, is mentioned by Wadding as in his possession, but only in manuscript; this was written at Paris in 1582.
In 1584 he edited and annotated the Censura Orientalis Ecclesiæ de præcipuis Hæreticorum dogmatibus, which was published by Stanislaus Socolovius.
