Ildefonsus or Ildephonsus (rarely Ildephoses or Ildefonse; Spanish: San Ildefonso; c. 8 December A.D. 607 – 23 January A.D. 667) was a scholar and theologian who served as the metropolitan Bishop of Toledo for the last decade of his life. His Gothic name was Hildefuns. In the Ethiopian Orthodox Tewahedo Church he is known as Dexius (ደቅስዮስ Daqsəyos) based on the Ge'ez translation of legends about his life. Although his writings were less influential outside of Hispania, Ildefonsus was canonised and remained a potent force in the Iberian Peninsula for centuries. Spanish missionaries, and to a lesser extent Portuguese ones, spread his ideas worldwide. Source: Wikipedia (en)
