New about Crimean jarlyks

I continue publishing my work «Geography of Crimean jarlyks of the 15th and 16th centuries» (2024). Today – the subsection «Berestej and Ratun» of the section «Little-known geographical names».

For my narrow topic, the exact localization of Berestej and Retan is irrelevant. No one doubts that these were some places near Tula.
