The alleged finding of the remains of a San Geronimo in 1853 afforded striking confirmation of an incident recorded by a Spanish Benedictine named Diego de Haëdo, who published a topography of Algeria in 1612. Haëdo sets forth the current legend that a young Arab who had embraced Christianity and had been baptized with the name of Geronimo had been captured by a Moorish corsair in 1569 and taken to Algiers. The Arabs endeavoured to induce Geronimo to renounce Christianity, but as he steadfastly refused to do so, he was condemned to death. Bound hand and foot he was thrown alive into a mould in which a block of concrete was about to be made. The block containing his body was built into an angle of the Fort of the Twenty-four Hours, then under construction. According to Samuel M. Zwemer, (see link below) in 1853 the Fort of the Twenty-four Hours was demolished, and in the very angle specified by Haedo the skeleton of Geronimo was found. The bones were interred at St Philippe. Into the mould left by the saint's body liquid plaster of Paris was run, and a perfect model obtained, showing the features of the youth, the cords which bound him, and even the texture of his clothing. This model was said to in the museum formerly at Parc du Galland, Mustapha Superior, Algiers.

This fable is drawn from Samuel M. Zwemer, (F.R.G.S.),(1867-1952), Call to Prayer (1920s), chapter II. He may have been inspired by a reference possibly to be found in John Reynell Morell, Algeria: The Topography and History, political, social and natural of French Africa, London, 1854 (this book has not been checked)
