Seven presumed local supernova events recorded in ancient annals over a 1500-year interval (from 185 to 1604) are discussed. Deficiencies in the available historical records are dealt with. No supernova-related data have been found in Babylonian, Greek or Roman chronicles, few in medieval European records. Medieval Arab records are more productive, while oriental sources (Chinese, Korean, Japanese) furnish information on all seven events (185 in Centaurus, 393 in Scorpius, 1006 in Lupus, 1054 in Taurus, 1181 and 1572 in Cassiopeia, 1604 in Ophiuchus), and also distinguish nova events from supernova events. The 1572 supernova was observed by Brahe, the 1604 supernova by Fabricius and Kepler (5 yrs before Galileo's telescope). Identification of remnants (pulsars, gas nebulae, radio source, X-ray source) with the chronicled events is discussed. Positions of the remnants are plotted on edge-on and face-on galactic maps. A unified investigation of all seven historical supernova events is recommended.
