 Abstract.
 In all ages, human beings have been trying hard to know
 astronomical phenomena to understand what the Universe is,
 where we are in and  what we are.
 With the assistance of large telescopes, satellites or
 explorers, we are getting closer to the horizon of the Universe.
 However, even with instruments using the most advanced technologies,
 we can never touch any phenomena that have already passed or have very
 long-term variability. Only surviving historical records have a
 possibility to tell us situations of each star of their times. In
 order to inspect stellar magnitudes of earlier eras and found unknown
 phenomena, we referred to historical star catalogues (Ptolemy’s ‘
 Almagest’ etc.) and charts kept in libraries all over the world. In
 this paper, we present historical records of stars and show possible
 long-term variability and unknown objects found by the analysis of
 these historical data.
