Only one volume survives, which deals with customs and organization of the Brethren and was first published in 1660.His other works include ''Historia de ingressu Polonorum in Valachiam cum Bogdano'' (1584) about the Polish invasion of Wallachia. The work was translated into Polish by Władysław Syrokomla in 1855.His 18-page ''Concerning the gods of Samagitians, and other Sarmatians and false Christians'' (''De diis Samagitarum caeterorumque Sarmatarum et falsorum Christianorum'', written  and published in 1615) provides a list of Lithuanian gods and is an important resource in the study of the Lithuanian mythology.
