Bulgarian medieval Philosophy and Natural Sciences were of great significance for the development of the natural sciences of the Orthodox Slavs and in the Balkan countries: Serbia, Russia, Wallachia and Moldova.

This article presents the spread of the natural sciences in the Principalities of Wallachia and Moldova by the preserved manuscripts and translations of Greek and Bulgarian works, such as “Physiologus”, “Hexaemeron” by Severianus of Cabala, Symeon’s “Miscellany”, (“Izbornik Svyatoslava” 1073), Erotapokriseis, etc.
