The continents are given as Europe, Asia, and Libya (Africa). The World Ocean is only seen to the west. The map distinguishes two large enclosed seas: the Mediterranean and the Indian (Indicum Pelagus).

WebIt describes the Moon's position as seen from the center of the Earth.) The parallax gives the distance in units of the Earth's radius: he finds this distance to be approximately 39 (at the time of observation). The average distance according to Ptolemy is 59. This is a good result for the accuracy of observations at that time. WebCanon of Kings. The Canon of Kings was a dated list of kings used by ancient astronomers as a convenient means to date astronomical phenomena, such as eclipses. The Canon was preserved by the astronomer Claudius Ptolemy, and is thus known sometimes as Ptolemy's Canon. It is one of the most important bases for our knowledge of ancient chronology .
