In this study, we apply our previously developed method to investigateancient transient sightings in order to derive consequences for modernastrophysical problems.We present case studies of three observations of socalled 'guest stars' in the 4th century CE which lasted several months each.These three observations had been suggested and discussed as possiblesupernovae but slow novae are also viable alternatives. Our carefulre-interpretation of the historical texts and the currently known objects inthe given fields shed new light on this topic. In particular, for the twoevents in 386 and 393 CE we suggest possible supernova identifications, whilein all three cases there are interesting candidates for past classical orrecurrent nova eruptions among known cataclysmic variables (CVs) and/orsymbiotic stars. The transient of 369, we suggest to explain as classical andpossibly recurrent nova instead of a supernova. The most plausible candidatesare BZ Cam, a CV with a possible nova shell, or CQ Dra, a naked eye multiplesystem perhaps able to permit an overwhelmingly bright nova with day-timevisibility.
