The Almagest also suggest that the Earth is at the center of the universe. The basis on which this is found is in the fact that six zodiac signs can be seen above Earth, while at the same time the other signs are not visible (Bowler, 2010, 57).
In the context of ancient astronomy, the Almagest implies that Earth is the central point around which the universe revolves. This idea is reinforced by the fact that six zodiacal constellations can be seen from our planet at the same time, while the others are not visible (Bowler, 2010, 57).
