They were three twin brothers, who, with Leonilla their grandmother, glorified God by an illustrious martyrdom in Cappadocia, probably in the reign of Marcus Aurelius. The most ancient acts of their martyrdom, published by Rosweide and Bollandus, place it in that country, and their relics were brought from the East to Langres in France, whilst the first race of French kings filled the throne. A copy of the acts of their martyrdom, which was sent from Langres by one Varnahair, to Saint Ceraunus, bishop of Paris, in the beginning of the seventh century, by an evident mistake or falsification, affirms their martyrdom to have happened at Langres; by which false edition, Ado, and many others, were led into the same mistake. From certain ancient writings kept at Langres, mentioned by Gualtherot in his Anastasius of Langres, Chatelain proves that these relics, with the head of Saint Mammes, a martyr, also of Cappadocia, were given by the emperor Zeno to a nobleman of Langres, who had served him in his wars. By him this sacred treasure was deposited in the church of Langres, in the time of the bishop Aprunculus, in 490, to be a protection against devils. The cathedral of Langres, which bears the title of Saint Mammes, is possessed of the head of that martyr in a rich shrine. A brass tomb before the high altar, is said to have contained the bodies of the three children who were thrown into the furnace at Babylon, mentioned in the book of Daniel: but Chatelain thinks it belonged to the three martyrs, whose bodies were given by the Emperor Zeno to the count of Langres. The church called of Saint Geome, or Sancti Gemini, that is, the twins, situated two miles from Langres, belongs to a priory of regular canons, and is famous for devotion to these saints, though great part of their relics was translated by Hariolf duke of Burgundy, and his brother Erlolf, bishop of Langres, into Suabia, and remains in the noble collegiate church of Saint Guy, or Saint Vitus, at Elvange. These holy martyrs are secondary patrons of the diocess of Langres, and titular saints of many churches in France and Germany.
