Theodemir of Iria

Theodemir or Theodomar (Galician and Teodomiro; died 847), was a bishop of Iria, in Galicia.

Background
At some point between year 818, when Bishop Quendulf was still alive, and 842 when king Alfonso II of Asturias died, Pelagius the Hermit saw mysterious lights, like a shower of stars, on the same hill in the forest near Libredon every night. He went and reported the phenomenon to Bishop Theodemir.

On July 25, 812, Theodemir gathered a small entourage and went to Libredon to see the phenomenon for himself. There, in the dense vegetation, they discovered a stone sepulchre in which rested the corpses of three men, who were immediately identified as the Apostle James the Great and two of his disciples, Theodore and Athanasius. Theodemir believed that this was in line with the Breviary of the Apostles, which taught that James was buried in an ark in Marmarica (arca marmárica), but he said "arca de mármol" or an ark of marble was meant.
