  Kidinnu   (Site not responding. Last check: 2007-11-07)
Kidinnu (also Kidunnu) (circa 400 BC – circa 310 BC) was a Chaldean astronomer and mathematician.
Kidinnu probably introduced the 19-year cycle known as the Metonic cycle into the Babylonian calendar in 383 BC.
In about 314 BC Kidinnu knew that the sidereal year was longer than the tropical year and therefore may have been aware of the precession of the equinoxes.

 Kidinnu - Wikipedia, the free encyclopedia
Kidinnu (also Kidunnu) (circa 400 BC – possibly 14 August 330 BC) was a Chaldean astronomer and mathematician.
In about 314 BC Kidinnu (if he was still alive at that time) knew that the sidereal year was longer than the tropical year and therefore may have been aware of the precession of the equinoxes.
A damaged cuneiform diary tablet from Babylon (Babylonian chronicle 8: the Alexander chronicle; BM 36304) mentions that "ki-di-nu was killed by the sword" on day 15 of probably the 5th month of that year, which has been dated as 14 August 330 BC, less than a year after the conquest of Babylon by Alexander.

 Kidinnu, the Chaldaeans, and ancient Babylonian astronomy
Kidinnu arrived at 29.530594 days, which is only 0.432 seconds more than the modern estimate of 29.530589 days.
Kidinnu's greatest discovery, however, is a system to predict the motion of the moon.
Kidinnu must have known that in the days of the legendary king Hammurabi (1792-1750), the earth's axis was directed to a point inside the Dragon and he must have been able to conclude that the axis of the earth was slowly changing its direction.

Kidinnu (also Kidunnu) (circa 400 BC – circa 310 BC) was a Chaldea n astronomer and mathematician.
Probably Kidinnu had made complex methods and equations for calculating the irregular movements of the Moon and other planet s and specially of the Sun.
So Kidinnu developed from Nabu-rimanni 's System A a more refined system (now called System B), used by the Chaldean astronomers to describe more clearly the motions of the Sun and planets.

Kidinnu arrived at 29.530594 days, which is only 4.32 seconds more than the modern estimate of 29.530589 days.
Kidinnu must have known that in the days of the legendary king Hammurabi (1792-1750 BC), the earth's axis was directed to a point inside the Dragon and he must have been able to conclude that the axis of the earth was slowly changing its direction.
It is tempting to assume that Kidinnu was executed by Alexander the Great on August 13, 329 BC, but it is far from certain that this is the correct reading of the tablet.

I also hope that the article of Hipparchos will be as good and acceptable for all as Kidinnu's is. And also about Cyprus regarding your changes at Aratus.
One at Kidinnu is rounded to 1s (29.53061343...d; 29.530614d was not mentioned to be raunded to 6th decimal with accuracy of 9/100s) and the other at Nabu-rimanni to 1/100s (29.53061401...d).
The problem is also an accuracy of their measurements, so it is rather hard for us where to round all these values and how to show them.

The texts include ephemerides, which are calculated tables predicting the times and locations of planets during significant planetary events, and procedure texts, which explain the rules for calculating the ephemerides.
To calculate planetary positions, Kidinnu and the other scribes used a technique of arithmetical progression known today as a zigzag function.
Unlike the early Greek astronomers, whose models were strictly qualitative(1), the Babylonian scribes attempted and achieved the ideal of quantitative prediction.

Kidinnu already knew the repeating period of the eclipses, later called the Saros cycle.
The actual reason of the shifting of the equinoxes, caused by the wobble of Earths axis, was not yet recognized.
Hipparchos supposed, probably like Kidinnu before him, a false measurement of the Precession with 100 years for 1°, perhaps in order to round up this slow movement on entire millenniums and to harmonize with the Babylonian number system.

In about 314 BC Kidinnu knew that the sidereal year was longer than the tropical year and therefore was probably aware of the precession of the equinoxes.
He had smoothed the way for the more accurate calculations of Hipparchos, since it seems that Hipparchos, who worked for a while in Babylon (near Kidinnu's city of Sippar) around 139 BC, knew Kidinnu's work.

 Movement of the Vernal Equinox Point - © Dr Shepherd Simpson
He was essentially ignored by other astrologers who incorrectly continued to use the older Kidinnu and Nabu-rimanni systems for relating the Vernal Equinox Point to the start of Aries.
However, the Vernal Equinox Point was steadily moving, which meant that astrologers needed to re-define their system against it.
This lead to what is now called System B [attributed to the Babylonian astrologer Kidinnu c 400 - 310 BC] in which the start of Aries lay at 8º from the Vernal Equinox Point.

He was able to do this because he possessed the sky map of Eratosthenes and age-old Babylonian observations and knew the theories of the great Kidinnu.
Unfortunately, Hipparchus ignored Kidinnu's calculation of the length of the solar year.
The Greek astronomer's estimate had an error of 6½ minutes, whereas the Babylonian was only 4½ short of the real length of the year.

 Hellenistic Astrology [Internet Encyclopedia of Philosophy]
The rivalry between the Seleucid and Ptolemaic kingdoms may be reflected in the astrologers' varying attributions of the origins of astrology to Egyptians or Babylonians (called the Chaldaeans).
Kidinnu and Soudines, two Babylonian astronomers mentioned by second century C.E. Vettius Valens, also contributed to Hellenistic astronomy and astrology.
One scholar of the history of astronomy (P. Schnabel, Berossus und die babylonisch-hellenistische Literatur, Leipzig 1923) argued that Kidinnu possessed a theory of 'precession of the equinox' prior to Hipparchus.

Kidinnu or Cidenas was a famous Babylonian astronomer (fourth century BCE?), one of the most important persons in the history of science.
A cuneiform Chronicle (http://www.livius.org/cg-cm/chronicles/chron00.html) (the Alexander Chronicle), which has recently dated to the reign of king Darius III Codomannus, mentions that a man named Kidinnu was put to the sword by the Macedonian king Alexander the Great on 14 August 329.

Jona Lendering: “I’d suggest naming an asteroid ‘Kidinnu.’ This Babylonian scientist is the forgotten founder of astronomy as a science.
I mean, he was not merely observing the skies, but actually applying complex mathematics to predict the phenomena.
In fact, he is far more important than the better-known Greek astronomers, who often used his results, which had been translated by Callisthenes, a courtier of Alexander the Great.” Joan forwarded a link to her article about Kidinnu.
