Meaning & History
Latinized form of Adamantios. This was borne by the 3rd-century Christian theologian Origenes Adamantius, who acquired the nickname because of his "character of steel", evidenced by severe ascetic practices (allegedly including self-castration based on a literal reading of Matthew 19:12 - "There are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven").
