or JUNOPU'LUS, JOANNES, the name given by Fabricius to a jurist of the later Byzantine period. In the title to one of his pieces, given in the of Leunclavius, he is called JOANNES, the son of JONOPULUS, and from his office CHARTOPHYLAX. (Ἰωάννης χαρτοφύλαξ ὁ τοῦ ʼιωνοπρούλου.) Fabricius in one place gives A. D. 1370 as the date at which he flourished; but says in another place that he flourished before Harmenopulus, who is placed by some in the twelfth century, by others in the fourteenth. [HARMENOPULUS] The following pieces are said to be by Janopulus:--1. Πιττάκιον Πατριαρχικόν, Breve Patriarchale, concerning a man who had married his mother's second cousin. It is inserted in the of Leunclavius (lib. iv. p. 291), and in the heading or preamble is ascribed to our author, whose name is given as above. 2. An exposition of ecclesiastical law, Περὶ γάμον τοῦ ζ̔́ βαθμον͂, De Nuptiis Septimi Gradus. This piece is inserted in the same collection as the foregoing (lib. iii. p. 204), but does not bear the name of Janopulus: it is ascribed to him by Bandini. Nicolaus Comnenus Papadopoli in his an authority of but little weight, cites the following as works of Janopulus: -- 3. Explicatio Canonum Poenitentialium Gregorii Thaumaturgi. 4. Responsum duodecinum ad Catholicos Iberiae. 5. Suggestio ad D. Patriarchum de Testinonio Clericorum. (Leunclav. Jus Gr. Rom. ll. cc. ; Fabric. Bibl. Gr. vol. xi. p. 643, xii. p. 208.)
