At the entreaty of John abbat of Raïthu he now composed his works, the Scala Paradisi and the Liber ad Pastorem; from the title ( κλῖμαξ ) of the first of these he gained his name of Climacus (Climakos). It contains his experiences in the spiritual life, with instructions for the attainment of a higher degree of holiness, and is dedicated to the abbat of Raïthu who afterwards wrote a commentary upon it (Patr. Gk. lxxxviii.1211–1248). Returning into solitude, John died at an advanced age early in the 7th cent. Boll: Acta SS. Mart. iii. 834: Migne, u.s. 631–1210; a new ed. of the Gk. text of his works was pub. in 1883 at Constantinople by Sophronius Eremites; Surius, de Probatis Sanct. Historiis, Mar 30.
