This is the second book of the authors with art therapy, dedicated to the Glagolitic.
This book contains other images as well as other methods of meditation based on the Glagolitic.
Officially, it is believed that the Glagolitic script (glagolitsa) was created by the Byzantine missionary Cyril to translate liturgical texts into the Old Church Slavonic language.
But there is another version, unofficial — that the Glagolitic script was created by Cyril on the basis of the ancient Slavic runic script. This is the version considered in the book.
Some Glagolitic letters, perhaps (but not all, and this is one of the assumptions from a number of sources), arose on the basis of the letters of the Greek alphabet in ancient times. The Greek alphabet is ancient, has been used to write the Greek language since the late ninth or early eighth century BC.
And the Slavic tribes in ancient times were quite active in trade relations in different parts of the world, so there was an interaction of cultures.
