Euhemeristic views are found expressed also in Tertullian ("De idololatria"), the "Octavius" of Marcus Minucius Felix and in Origen. Arnobius' dismissal of paganism in the fifth century, on rationalizing grounds, may have depended on a reading of Cyprian, with the details enormously expanded. Isidore of Seville, compiler of the most influential early medieval encyclopedia, devoted a chapter "De diis gentium" to elucidating, with numerous examples and elaborated genealogies of gods, the principle drawn from Lactantius, "Quos pagani deos asserunt, homines olim fuisse produntur." ("Those whom pagans claim to be gods were once mere men.") Elaborating logically, he attempted to place these deified men in the six great periods of history as he divided it, and created mythological dynasties. Isidore's euhemeristic bent was codified in a rigid parallel with sacred history in Petrus Comestor's appendix to his much translated "Historia scholastica" (written ca. 1160), further condensing Isidore to provide strict parallels of figures from the pagan legend, as it was now viewed in historicised narrative, and the mighty human spirits of the patriarchs of the Old Testament. Martin of Braga, in his "De correctione rusticorum," wrote that idolatry stemmed from post-deluge survivors of Noah's family, who began to worship the Sun and stars instead of God. In his view, the Greek gods were deified descendants of Noah who were once real personages.
