He worked as a sacristan in several Estonian churches, including Põltsamaa (1692–1698) and Karula (1698–1715).[1]
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".[1]
His most important work was Latin-language Grammatica Esthonica ... which gave the overview of grammar of the North Estonian language.[1]
