Mather had written HEAVENS ALARM on the occasion of a 1680 comet, and these works demonstrate not only Mather's interest in science and natural phenomenon, but his attempts to reconcile scientific observation with religious faith. In the KOMETOGRAPHIA..., however, we find a work of a character wholly different from the two other sermons - a treatise on the nature and history of "blazing stars," written at a distance somewhat removed from their theological significance, and incorporating observations on the trajectory and physical demeanor of Halley's Comet (the former recorded by Boston printer John Foster).
