A possible measurement of the top quark mass by an energy scan of the t{anti t} threshold region at e{sup +}e{sup {minus}} colliders of {radical}s = 250--500 GeV is discussed. With an integrated luminosity of 1 fb {sup {minus}1} devoted to the energy scan, a top quark mass of about 150 GeV can be determined with an accuracy of {approx}0.3 GeV, with a comparable systematic uncertainty arising from the few % errors in the {alpha}{sub s} measurement at LEP-I. The possibilities of studying {Gamma}{sub t} and Higgs boson effects are also discussed. 10 refs., 12 figs., 4 tabs.
