Datation possible to the new appendix at the beginning of Ms. 334 which mentions Ioannes the Protopsaltes (1730s), who was until 1734/1736 still Lampadarios. The Kratematarion (Ms. 336) mentions one composer just as "Lampadarios" and only once as "Ioannes the Lampadarios". Both anthologies are written by the same hand, not far from the style of Ioannes' autographs.
