Tradicinių kalendorinių švenčių semantika : monografija

Abstract

In 1855 the famous astronomer of the old Vilnius observatory, Matvej Gusev (1826-1866), described the stick which was used as a calendar in the times of the Grand Duchy of Lithuania. The signs on the stick represent the sequence of months. They are divided by the symbols of moon phases into weeks of nine days. The calendar is of a lunisolar kind. The usage of such calendar system in Lithuania of the Middle Ages is confirmed by the features of the archaeoastronomical arrangement on the Birute Hill near the seashore in Palanga. The principles of the functioning of the arrangement are based on the fixation of the azimuths of sunset or sunrise, as well as the path of the moon in Meton's Cycle.
