This paper is based on the assumption that the ‘egocentric perspective’ of the
human mind acted as an efficient psychological factor for evolving the astrological
doctrines. We adopt a psychological approach to studying the relation between historicalsocial
events and the astrological doctrines in the medieval period. In its focus, this study
deals with the two celestial phenomena observed in the Middle East from the beginning of
the 14th century to that of the 15th one, where astrological interpretations or the
prognostications had political, social and historical effects. The examples have been
selected from the primary historical sources. They are Comet 1402 D1 and the unordinary
conjunctions between Mars and Saturn. Considering them in various contexts, it is shown
how those phenomena were ‘the cause of anthropocentric historical events’ such as wars,
or identified as ‘the justifier of social or natural accidents’ like epidemics. The explanation
of the role astrology played in such events, in particular, and its impact upon societies, in
general, must be sought in the psychical effect caused by the astrological ideas on the
human mind and its relation with the physical world. We conclude that as the human
egocentric mind was a main cause of the formation of astrology, astrology itself penetrated
into the consciousness of the human mind and objectively appeared in the physical world,
and therefore conducted history in a specific direction. It is shown that this effect was so
extended to give birth to the astrological history. In addition, having classified the four
ways of interpreting the celestial phenomena in the ancient – medieval period (meteorological/
weather prognostication, natural philosophical, meteorological/atmopheric, astrological),
we briefly noticed the situation of the astrological dogma in Islam and the
methodological distinction between astrology and astronomy by Avicenna in that period.
