The pastor and poet Michael Albinus in Danzig (Gdańsk), who was born in nearby Pröbbenauin in the Polish–Lithuanian Commonwealth.
[1] , later wrote that Plavius was active as a private teacher, providing basic instruction in the Latin language.

Plavius maintained relationships with other poets, such as Martin Opitz, Johann George Moeresius, and Peter Crüger.
