The earliest school-books were here composed.

Peter Moghila's own "Shorter Catechism" is still referred to.

The Slavonic grammar and lexicon of Lavrenty Zizanie-Tustanovsky and Melenty Smotritzky continued in use until supplanted by those of Lomonosoff one hundred and fifty years later.

The most important factor, next to the foundation of the famous Academy, was, that towards the middle of the seventeenth century learned Kievlyanins, like Simeon Polotzky, attained to the highest ecclesiastical rank in the country, and imported the new ideas in education, which had been evolved in Kieff, to Moscow, where they prepared the first stable foundations for the future sweeping reforms of Peter the Great.
Literature continued to bear an ecclesiastical imprint; but there were some works of a different sort.

One of the compositions which presents a picture of life in the seventeenth century--among the higher and governing classes only, it is true--is Grigory Kotoshikin's "Concerning Russia in the Reign of Alexei Mikhailovitch." Kotoshikin was well qualified to deal with the subject, having been secretary in the foreign office, and attached to the service of Voevoda (field marshal), Prince Dolgoruky, in 1666-1667.
