"Kirik the Novgorodian’ time calculus" - in memory of R.A. Simonov (1929-2023)

Rem Aleksandrovich Simonov was a prominent scientist, and researcher of the natural scientific knowledge of Medieval Rus’ (“Ancient Rus'”), the author of remarkable works devoted to the study of the natural scientific thought of ancient Russian authors. Once upon a time, he involved the author of this report in the analysis of the well-known work of Kirik the Novgorodian, “Teaching on Numbers” (“Uchenie o Chislakh”, or in full, “Uchenie im zha vedati cheloveku chisla vsekh let”). The report is dedicated to the works of Kirik the Novgorodian with some inclusion in the historical context of 12th-century Veliky Novgorod. Particular attention is paid to the daily division of time proposed by Kirik, including the division of the day into “fractional hours” - in comparison with the division of daily time in the works of scientists from other countries in times close to the 12th century.
