The Horologion, published in the Printing house of the Kiev-Pechersk Lavra in late 1616 or early 1617, contains a mixed liturgical terminology that goes back to both the South Slavic tradition of translations of the Jerusalem Typicon and the East Slavic one. At the same time, the Kievan Horologion contains lexemes that go back to the older South Slavic translations of the Jerusalem Typicon. It can be assumed that these lexemes are not borrowed directly from the South Slavic sources, but are inherited from later East Slavic versions of the Horologion.
