There is more and more evidence that the Arabic script was the second script in Tartary, had Russian roots and, possibly, was created as a special language for the Horde - the army, simultaneously performing a cryptographic function. The illustrations given eloquently testify to this.
Egor Klassen in his "New materials for the ancient history of the Slavs in general and the Slavs-Rus before the Rurik time, especially with a light sketch of the history of the Russians before the birth of Christ", 1854, writes:
And that the Slavs had literacy not only before the general introduction of Christianity between them, but also long before the Nativity of Christ, is evidenced by the acts that elevate the literacy of the Slavs-Russ from the tenth century ago - to deep antiquity, through all the dark periods of history, in which occasionally, here and there, but the element of the Slavic-Russian people with its characteristic type is clearly visible.
In the 6th century, the Byzantines already speak of the northern Slavs as an educated people who have their own letters, called a drop cap. The root of this word has survived to this time in the words: letter, primer, literally and even in the second letter of the alphabet (beeches) … From the 2nd to the 7th century, we often find in the Scandinavians and Byzantines hints that the Slavs were an educated people, possessed with many knowledge and had their own letters … The Scythian King called Darius with an abusive letter to battle as early as 513 BC.
Here is what Mauro Orbini writes about the initial letter in his work "Slavic Kingdom":
The Slavs have two types of letters, which neither the Greeks nor the Latins have. One species was found by Cyril and is called the Cyrillic alphabet (Chiuriliza), the other by the blessed Jerome, and it is called the initial letter (Buchuiza). These two types of writing were found by Blessed Jerome and Cyril, about which the Slavs, especially the Czechs and Poles, have an enduring memory.
Below Orbini writes about the Slavic tribe of Marcomans, citing also separate fragments of the letter:
Other deeds and wars of the Marcomans can be found in Dion and Wolfgang Latius. We will add here a few letters that the Marcomanians used to write. These letters were found in the old Frankish chronicles, which also contained the genealogy of Charlemagne [748-814].
The rest of the letters, according to Latius, could not be read due to the dilapidation of the book in which the aforementioned ones were found. However, Eremey Russky, in the place where the talk about the Marcomanians, says that there was not much difference between the Marcomanian letters and the Slavic ones.
Ibn-El-Nedim and Ibn-El-Nedim lead to his essay "Book of painting to sciences" a snapshot of an ancient Slavic letter, which he found in the possession of a Caucasian inhabitant embedded in a white tree.
As depicted by the ancient authors Slavic letters (Bukvitsa), and how it is reflected in historical, linguistic and archaeological evidence, a number of pictures are given.
