The festival of Corpus Christi – the body of Christ – was first celebrated in Priego in the mid-16th century, and is likely to have been encouraged by the evangelist known as “the Andalucían Apostle”, Saint John of Ávila: he wrote a treatise entitled Concerning the Holy Sacrament, and between 1525 and 1569, he preached extensively in the provinces of Córdoba, Granada, and Jaén. In Priego, he enjoyed the patronage of the senior local clergyman Marcos López, the founder of the College of Saint Nicasio: it was this cleric who took charge of organising the celebration of Corpus Christi.
