Ptolemy

That is almost a correct description. Ptolemy's model was not incorrect, because it predicted the positions of the planets quite accurately. So accurately that no-one thought to question it for over a thousand years.

But in the end people decided to try for a more accurate model, and after a couple of attempts a model came up that is now accepted everwhere, which was devised by Johannes Kepler and published in 1609. It was accepted after the discovery of the law of gravity and the laws of motion.

Before that there were some big arguments about which was the right model, and especially about whether the Earth is at the centre, or the Sun.

Kepler's model has the Sun at the centre and this is now accepted because the later discoveries showed that the Sun is far more massive than the planets, so it sits at the centre while all the planets orbit round it.

So far, it has not been determined exactly how Ptolemy XIV died. Historians assume that Cleopatra had him poisoned, but remember this is just an assumption, not a hard fact.

He ate a lot of pie.

Ptolemy II Philadelphus died in -246.

It was Bailly who saw a two stage process of sweeping away the old and establishing the new.

I think she had one child, a son.

From Octavia Grove (I also have one child, a son!)

Ptolemy knew of the seven classical planets: Mercury, Venus, Mars, Jupiter, Saturn, the Sun, and the Moon. These were the celestial bodies visible to the naked eye that were thought to move around Earth in the geocentric model of the solar system.

No one is certain, but many believe that his sister Cleopatra hired someone to murder him. But no cause of death has been confirmed.

Yes, Ptolemy developed a method to determine true north by using a sundial. By observing the shadow cast by the sundial at different times of the day, one could align the sundial's gnomon (the part that casts the shadow) with true north.

Claudius Ptolemaes was born in AD 90 and died AD 168. He was born in Egypt and made himself king even though he wasn't a dynasty. he worked as an Egyptian astronomer. his biggest obstacle was showing the formulas he used to calculate the information he wrote in his book the Almagest.

He Was Married to Queen Elizazbeth

The center of the universe would be defined in astronomical terms as the place where the Big Bang took place some thirteen and a half billion years ago. At this point in time it is probably empty. No object would still be there. Unless someone has erected a plaque, perhaps, to mark that historically important location.

Claudius Ptolemy synthesized and extended Hipparchus' system of epicycles and encentric circles to ezplain his geocentric theory off the solar system.

Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.

late 1500s

========================

There's nothing too startling about that answer, until you

consider the fact that Ptolemy died around the year AD 178.

Yes, he wrote about the "geocentric" (Earth centered) theory around the year AD 150.

He didn't "come up with" the theory, but he perfected it.

Not all of Cleopatra VII's children died. She had four known children: Caesarion, Alexander Helios, Cleopatra Selene II, and Ptolemy Philadelphus. While Caesarion was killed shortly after Cleopatra's death, Alexander and Cleopatra Selene survived and were taken to Rome, where Cleopatra Selene later married King Juba II of Mauretania. Ptolemy Philadelphus's fate remains uncertain, but he is believed to have lived into adulthood.

Ptolemy was a Greek-Roman mathematician, astronomer, and geographer who lived in Alexandria during the 2nd century CE. He is best known for his work "Almagest," which presented the geocentric model of the universe and dominated astronomical thought for over a millennium. Ptolemy also authored "Geographia," which compiled knowledge of the world's geography and introduced concepts like latitude and longitude. His contributions laid the groundwork for future scientific developments, influencing both Islamic and European scholars during the Middle Ages and the Renaissance.

Revived and influenced by Ptolemy's work, leading to advancements in cartography and mapmaking techniques. Ptolemy's geography provided a valuable foundation for understanding the world and mapping techniques that were further developed and used in the Renaissance period.
