Soeiro Viegas
He spent eight or more years of his episcopate in Rome, where he was on behalf of King Afonso II in 1211–1212 and attending the Fourth Lateran Council in 1215–1216.
[5] During that year, he served seven times as a papal judge-delegate in a dispute between the diocese of Coimbra and the monastery of Santa Cruz.
He and Vicente were instrumental in having Innocent reissue the bull Manifestis Probatum on 16 April 1212, confirming Alfonso II's right to the throne.
According to the De itinere Frisonum, there he asked Innocent for permission to employ crusaders in a planned Portuguese offensive against the Almohads, but the pope refused.
[7] Soeiro remained in Rome throughout 1216, relitigating Alfonso II's dispute with his sisters, which resulted in a new bull from Innocent III in the king's favour, Cum olim charissimus, on 7 April 1216.
[8] On 17 April 1217, in a charter praising him for his successful litigation in Rome, Alfonso II placed Soeiro and his diocese under royal protection.
After the victory, Soeiro and the other leaders of the expedition wrote to the new pope, Honorius III, requesting retroactive authorization and leave to employ the crusaders for another year against the Almohads.
[14] It was probably in pursuit of these goals that Soeiro commissioned Goswin of Bossut to write the De expugnatione Salaciae carmen ('Song of the Conquest of Alcácer').
[15] The poet acknowledges Soeiro disappointment in the aftermath of the siege when he writes that "one man, and this itself is a great injustice, remained at Alcácer unrewarded and won nothing thereupon.
"[16] Soeiro faced opposition in his own cathedral over his long absence on a military campaign, especially from his dean, Vicente Hispano.
The Vita sancti Antonii credits him with helping put together a dossier for Anthony of Padua's canonization.
[22] His epitaph, trumpeting his greatest achievement, reads, "Lord Suarius, Bishop of Lisbon, lies here, who during the reign of Afonso II conquered Alcácer do Sal from the Moors in the year 1217.
