In the nave of the Epistle, there are two stained glass windows that depict Acisclo and Victoria, martyrs and patron saints of Córdoba. Created by Antonio Mesa, the siblings are represented in their youth, dressed in clothing typical of their time, the 3rd century, and with elements that allude to their martyrdom.
Among the stained glass windows that adorn the temple is the one of the martyr Saint Acisclo. Acisclo, patron of Córdoba, is depicted wearing historicist garments that recreate those of the 3rd century when he lived. He was decapitated after enduring numerous torments, carrying the sword of his execution and the bloody wound to his neck. His left hand holds the palm of martyrdom, which alludes to his death for his faith in Christ.
