Brussels, and in 1467 decided to fund a chapel dedicated to Ferdinand the Holy Prince at the Church of St. Anthony in Lisbon. To this end, Isabella dispatched Frei João Álvares to Rome to petition the pope for religious honors for her brother, possibly even beatification, the first step to formal sainthood. At Álvares's request, bulls were issued by Pope Paul II in 1470 granting permission for the Lisbon chapel and indulgences to anyone who attended an anniversary mass for Ferdinand. Although a contract was signed between Álvares and Lisbon municipal authorities in November 1471 to begin the chapel, the death of both Paul II and Isabella around this time probably prevented the campaign from going forward, with the result that Ferdinand remained unbeatified and uncanonized. King Afonso V of Portugal is reported to have invoked the memory of the martyrdom of his uncle in his three Moroccan campaigns of 1458, 1463/4 and 1471. In the last campaign, the conquest of Asilah, Afonso finally captured Tangier. In the aftermath, negotiations were opened between Afonso and the Moroccan strongman Muhammad al-Sheikh to deliver the bones and bodily remains of Ferdinand, which were still in Fez. These negotiations dragged on for a while, but the remains were finally obtained by the Portuguese in 1473 (or perhaps 1472) One version relates that a disgruntled Moroccan courtier, said to be the ruler's own nephew, seized the coffin containing Ferdinand's body, smuggled it out of Fez, and brought it all the way to Lisbon to sell to the Portuguese king for a considerable sum. There were subsequently great ceremonies in depositing the bodily remains in Ferdinand's tomb in Batalha. The cult of Ferdinand continued into the 16th and 17th centuries. King Manuel I of Portugal had the sculptor Nicolau Chanterene sculpt a statue of Ferdinand on the left side of the magnificent western door of the Jerónimos Monastery c. 1517. In 1538–39, in accordance with an endowment of the late dowager-queen Eleanor of Viseu (the widow of John II) a retable was commissioned depicting the life and sufferings of Ferdinand, painted by Cristóvão de Rodrigues, to be set up in Ferdinand's chapel at Batalha (alas this retable has long since disappeared). The saintly cult of the Ferdinand the Holy Prince fell foul of the ever-stricter rules of the Catholic Church, which sought to discourage cults of unbeatified and uncanonized persons. The only clear evidence of
