Martinho de Soure or Martin Arias was the son of Manuel Aires and Argia. He entered into a life of clerical service under the care of Bishop Maurice of Coimbra. Bishop Maurice was the cousin of Martinho's father, who requested he oversee his son's training.
As an ordained priest, Martinho led an exemplary life and was admired for his virtue and charity to the needy. Around 1124 he moved to the border town of Soure with his brother Mendo. He established an ecclesiastical chapter to restore the church and give spiritual assistance to people who had been attacked by Muslims in 1117.
Very dear to the people, in 1144, the Muslim governor of Santarém Abu Zakaria occupied and destroyed Soure, dispersing a large part of the population to Santarém. There, he predicted the conquest of the city by Afonso I of Portugal and was sent to Évora, Seville, and Córdoba, where he was tortured and died in prison by Abu Zakaria's order in 1146.
The monk Salvado de Santa Cruz wrote about the life of Saint Martinho de Soure around 1150.
