Fandilus was a ninth-century monk and priest from Spain who lived during the period of Muslim rule in Córdoba. Born in Guadix around 815, he was educated in a monastery and later served as a priest at the Abbey of Saint Redeemer in Peñamellaria. He is recognized as a martyr for his religious convictions during the reign of Muhammad I, which ultimately led to his execution.
Life and death

After his monastic training, Fandilus was ordained as a priest near Córdoba. During the persecutions of Christians under the rule of Muhammad I, he was sentenced to death for his Christian faith and for allegedly insulting the prophet Muhammad. He was executed by decapitation, and his body was subsequently displayed in public.
Veneration
The details of his martyrdom were recorded by Saint Eulogius in the written work titled Memoirs of the Martyrs. Because of his death, he is venerated as a saint within the Catholic, Anglican, and Orthodox traditions. His feast day is observed annually on June 13.
