the presence of the Ferdinand cult inside a regular church outside the Batalha chapel was the retable dedicated to Ferdinand set up at the church of Our Lady of the Olive Grove in Guimarães in 1472, in celebration of the imminent translation of the relics. In 1614, Martim Afonso Meixa, Bishop of Leiria, prohibited the Ferdinand cult at Batalha on account of his not being beatified. Nonetheless, the 1595 hagiography by Jerónimo Román and the 1623 history written by Frei Luís de Sousa tried to encourage it, suggesting masses for Ferdinand the Holy could be carried out subsumed in masses for All Saints. Jorge Cardoso included him in his Agiológio Lusitano (1666). The 1634 papal encyclical Coelestis Hierusalem issued by Pope Urban VIII prohibited popular cults of unbeatified and uncanonized persons "unless they proved to be of time immemorial". The Bollandists used this clause to insert Ferdinand the Holy Prince in the "June 5th" entry of their Acta Sanctorum in 1695, controversially including a rare image of him with a halo. Restrictions on the religious cult did not prevent the continuation of a secular cult of Ferdinand, connected to the narrative that Ferdinand was a voluntary martyr for Portugal's imperial mission. The Portuguese poet Luís de Camões made a brief mention of Ferdinand in his epic 1572 poem Os Lusíadas (Canto IV, stanzas 52–53), asserting Ferdinand had given himself to martyrdom voluntarily for patriotic reasons, "a sacrifice to love of country made, that not for him strong Ceuta be o'erthrown, the public weal preferring to his own." Perhaps surprisingly, the Fernandine legend got another gust of wind after the 1580 Iberian Union with Spain. The Spanish playwright composed a drama La Fortuna Adversa del Infante D. Fernando de Portugal in 1595–98 (sometimes attributed to Lope de Vega), which was probably the basis for the more famous 1629 Baroque play El príncipe constante by Calderón. , the exiled Archbishop of Evora published a more modern version of Ferdinand's story in 1836. In English, the story of Ferdinand the Holy Prince was told in an 1842 poem "The Steadfast Prince" by Richard Chenevix Trench The story was also turned into a 19th-century pulp historical fiction novel, The Constant Prince, by Christabel Rose Coleridge. The Ferdinand legend received another lift in the 20th century, particularly encouraged by the Portuguese Estado Novo, which was keen on cultivating icons of nationalism and overseas glory. Ferdinand
