"Among the devotional objects mentioned in the inventories (made during the trial investigations 1307-1312, TN) relics and reliquaries feature prominently. (...) One devotional trend that the Templars, especially in southern France, seem to have picked up was that of the fourth-century martyr St Blaise, bishop of Sebastia.
Saint Blaise was remembered and venerated as a skilled
physician and judging from the inventories he was held in high regard in
the Order in southern France and Spain. St Blaise was the patron of the
Templars’ chapels at Hyères and Montfrin in Provence; and his relics
are recorded in the inventories of the Templars’ houses in Avignon and
Grasse, also in Provence, which both had altars dedicated to him, and at
Peñíscola in Catalonia.
His cult may have spread as far as Paris, where
one of the altars in the main Templar church was dedicated to him; the
Templar sergeant Peter Maurini for one confessed during the trial that
the Order possessed what he believed to be either the head of Saint
Peter or Saint Blaise."
