The pope does not give up on his hope of converting the natives.

In 1351, Pope Clement VI had endorsed an expedition by Majorcan captains Joan Doria and Jaume Segarra, with the object of bringing Franciscan missionaries, including twelve converted Canarian natives (apparently seized by previous Majorcan expeditions), to the islands.

Whether this expedition ever set out is uncertain.

Apocryphal legend relates the missionaries succeeded established an evangelizing center at Telde (on Gran Canaria), which the pope elevated to the 'Diocese of Fortuna' (although no bull to that effect has been found), until they were expelled in a native uprising in 1354.

More confident is the bull issued in July 1369 by the Avignon Pope Urban V erecting the diocese of Fortuna and appointing Fr. Bonnant Tari as bishop, and a follow-up bull of September 1369 instructing the bishops of Barcelona and Tortosa to dispatch ten secular and twenty regular clergy to preach to the Canarians in their native languages, but whether this actually set out or just remained a paper project is also uncertain.
