(Ἰωάννης ὁ Κλίμακος), surnamed the Learned (ὁ Σχολαστικός), a Greek writer who lived in the sixth century of the Christian aera.
His original name was Joannes, and he was called Climacus on account of a work written by him, which was entitled Κλίμαξ. He took orders, and although the learned education which he had received seemed to have destined him for a life among scholars, he lived during forty years with monks of the most rude and illiterate description, till he was chosen abbot of the convent on Mount Sinai, where he died at the age of one hundred, or thereabouts, on the 30th of March. The year of his death is uncertain, but it was probably in the beginning of the seventh century. (A. D. 606?)
