Pelagius (Spanish: Pelayo, Paio or Pelagio) was a hermit or anchorite[2] who lived in Solovio in the Libredón forest in 813 AD.
[7] Pelagius, amazed at these lights, appeared before Bishop Theodemir of Iria Flavia (now called Padrón) to tell him about the miracle.
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.
[11] This chapel was initially converted into a church in 829 and was later refurbished in the pre-Romanesque style in 899, by the order of Alfonso III.
Finally in 1075, under the reign of Alfonso VI, the construction of the Santiago de Compostela Cathedral began.
