1680 – Christopher Sandius Jr., the author of many Arianist tracts, died at age 36. Born in Königsberg, Germany into an avidly anti-Trinitarian family, he became a proofreader when other work was denied him because of his beliefs. His Nucleus historiae ecclisiasticae is an important work in 18th century theology and claimed the attention of the likes of Newton and Spinoza.
