Some sources of symbolism of H. S. Skovoroda In Pratsi Ukrayinskoho Vysokoho Pedahohichnoho Instytutu im. M. Drahomanova. Zbirnyk, vol. II, 1934, pp. 3-21.

In this article, Dmytro Chyzhevskyi explores symbolism in Skovoroda's works and presents images of emblems created by the philosopher. The author proves that Skovoroda's emblems were inspired by Amsterdam symbols. Chyzhevskyi illustrates the parallels between the symbols in the Amsterdam collection and those in Skovoroda's works, including “The Alphabet of the World”, the dialogue “The Ring”, and the “Serpent of Israel”. The author argues that the idea of symbolic imagery and the Amsterdam collection were already widespread in Ukraine during Skovoroda's lifetime.
