1. De natura lucis. 2. Philolaus. 3. Astronomia philolaica, opus novum, in quo motus planetarum per novam et veram hypothesen demonstrantur. 4. Astronomia philolaica fundamenta clarius explicata et afferta adversus Zothi Wardi impugnationem.

He also wrote a piece or two upon Geometry and Arithmetic. In 1661, he paid Hevelius a visit at Danzig, for the sake of seeing his optical and astronomical apparatus. Afterwards he became a presbyter at Paris, and died there in 1694.
