アブド・アッラフマーン3世
Pelagius was left by his uncle at the age of ten as a hostage with the Caliph Abd-ar-Rahman III of al-Andalus, in trade for a clerical relative previously captured by the Moors, the bishop Hermoygius. The exchange never occurred, and Pelagius remained a captive for three years. According to the testimony of other prisoners, his courage and faith was such that the Caliph was impressed with him when he had attained the age of 13. The Caliph offered him his freedom if Pelagius converted to Islam. The boy, having remained a pious Christian, refused the Caliph's offer.
