This article shows how the original text of the 17th century cosmography (known as “Blaeu’s Cosmography”, also known as “The Grand Atlas”) corresponds with its Old Slavonic translation made by Epifany Slavinetsky in Moscow. It is shown that Slavinetsky doesn’t follow the original precisely, but introduces a certain correspondence between Latin and Old Slavonic grammatical structures. We also believe that this translation is an example of “scholar” language register.
