Historia Carpato-Ruthenorum is the earliest history of “Carpatho-Rusyns” known to us, written by the Subcarpathian Uniate priest Michael Lutskay (Михаил Лучкай). Historia Carpato-Ruthenorum was written in Latin, in Cassovia (modern-day Košice, Slovakia) in 1843. This document is a modern reprint, which comes from an academic journal printed in Slovakia in 1983, and includes a parallel translation into Ukrainian and a forward by Yuri Sak of Uzhhorod State University. Lutskay is a topographic name, indicating that the author came from the village of Velyki Luchky (Nagylucska in Hungarian) in modern-day Transcarpathia, Ukraine. His family name was Pop (Поп). Michael Lutskay is also the author of Grammatica Slavo-Ruthena which can also be considered the first Carpatho-Rusyn grammar book.
