Im thinkin that it was made when he decided to look up at the sky one night and decided he would make an astronomical observation. idk just that's how i would make an oservation of the sky.

The astronomical canon was a compilation of mathematical tables and astronomical data used for making astronomical calculations and observations. It helped astronomers accurately predict the positions of celestial bodies in the sky.
Copernicus was the first to show, in a systematic and mathematical way, that a helio-centric solar system made astronomical observations easier to understand. Ptolemy's system worked (well, sort of) in explaining what we see, but it was incredibly complicated.
In "Great Astronomers," Robert Stawell Ball explores the evolution of astronomical thought, starting with the influential contributions of Ptolemy, whose geocentric model dominated for centuries. Ball highlights how Ptolemy's work, particularly the "Almagest," laid the groundwork for future astronomical studies by synthesizing earlier knowledge and offering detailed observations. The book then traces the progression of ideas through key figures and discoveries leading up to the nineteenth century, illustrating the gradual shift from geocentrism to heliocentrism and the scientific revolution that transformed our understanding of the cosmos.
The Almagest, originally titled "Mathematical Syntaxis," was written by the ancient Greek astronomer Claudius Ptolemy in the 2nd century. This work compiled and summarized the astronomical knowledge of the time, presenting the geocentric model of the universe and detailed observations of celestial bodies. It became a key reference for astronomers for many centuries, influencing both Islamic and European astronomy.
Ptolemy would have made his observations in Egypt probably Alexandria around AD120 up to his death in AD168.
