The brightest optical flash from a gamma-ray burst (GRB) was, briefly, anaked-eye object. Several other GRBs have produced optical transients onlyslightly fainter. We argue that, based upon the recently accumulated data fromhundreds of GRB transients, many such optical events should have been visibleto the unaided eye in the course of human history. The most likely repositoriesof such observations are historical records from the Orient, and we havelocated and discuss a number of candidates. We also consider the value of suchobservations, should any very likely ones be uncovered, to modern astrophysics.

Could bright gamma-ray burst optical transients have been recorded historically?
