Martin of Soure was a 12th-century Portuguese priest and canon of the Coimbra Cathedral. Born around 1050 to Manuel Aires and Argia, he received his clerical training under Bishop Maurice of Coimbra. Known for his charitable nature and virtuous conduct, he eventually moved to the border town of Soure around 1124. There, he worked alongside his brother Mendo to establish an ecclesiastical chapter, providing spiritual support to those affected by Almoravid attacks.
Martyrdom and death
Following the destruction of the Knights Templar Castle in Soure by the Almoravid governor Abu Zakaria, Martin was taken prisoner. While in captivity, he prophesied that Afonso I of Portugal would eventually capture Santarém to avenge the town. This prediction led to his transfer through Évora and Seville before reaching Córdoba. He died in prison there in 1146 after being subjected to torture.
Veneration
Recognized as a saint, Martin is commemorated in both Catholic and Anglican traditions. His life and death were documented by the monk Salvado de Santa Cruz around 1150. He is honored with a feast day on January 31.
