Johann Hornung (1660 Tallinn – 1715) was a Baltic-German Lutheran clergyman and language enthusiast.[1]
He worked as a sacristan in several Estonian churches, including Põltsamaa (1692–1698) and Karula (1698–1715).
With Adrian Virginius, he translated New Testament into North Estonian. 1694 he published religious book "Önsa Luterusse Laste Öppetuse ...", and he was a co-author of the religious book "Ma Kele Koddo ning Kirgo Ramatu".
His most important work was Latin-language Grammatica Esthonica ... which gave the overview of grammar of the North Estonian language.
