Based on this, he argued that Naburimannu developed the Babylonian System A of calculating solar system ephemerides, and that Kidinnu later developed Babylonian System B. Otto E. Neugebauer has remained reserved to this conclusion and disputed Schnabel's further inferences about Naburimannu's life and work.

* The colophon of two Babylonian System B lunar ephemerides from Babylon ( see ACT 122 for 104 – 101 BC, and ACT 123a for an unknown year ) say that they are the tersitu of Kidinnu.

He argued that Naburimannu developed the Babylonian System A of calculating solar system ephemerides, and that later Kidinnu developed the Babylonian System B.

* Babylonian / Chaldean :- Naburimannu, Kidinnu, Soudines

To the Babylonian astronomer Kidinnu ( in Greek or Latin, Kidenas or Cidenas ) has been attributed the invention ( 5th or 4th century BC ) of a system " B " for predicting the position of the moon, taking account that the moon continually changes its speed along its path relative to the background of fixed stars.

Babylonia had already been conquered as far as the marshes of the Chaldaeans in the south, and the Babylonian king put to death.

" ... Babylonian astrologers and astronomers were often called " Chaldaeans.

The Babylonian Chronicles were written from the reign of Nabonassar up to the Parthian Period, by Babylonian astronomers (" Chaldaeans "), who probably used the Astronomical Diaries as their source.

* The Greek geographer Strabo of Amaseia, in Geography 16. 1 –. 6, writes: " In Babylon a settlement is set apart for the local philosophers, the Chaldaeans, as they are called, who are concerned mostly with astronomy ; but some of these, who are not approved of by the others, profess to be writers of horoscopes.

In Old Babylonian astronomy, Ea was the ruler of the southernmost quarter of the Sun's path, the " Way of Ea ", corresponding to the period of 45 days on either side of winter solstice.

In the earliest Indian astronomy texts, the year was believed to be 360 days long, similar to that of Babylonian astrology, but the rest of the early astrological system bears little resemblance.

Ptolemy's catalogue is informed by Eudoxus of Cnidus, a Greek astronomer of the 4th century BC who introduced earlier Babylonian astronomy to the Hellenistic culture.

The oldest catalogues of stars and constellations are from Old Babylonian astronomy, beginning in the Middle Bronze Age.

The classical Zodiac is a product of a revision of the Old Babylonian system in later Neo-Babylonian astronomy 6th century BC.

Greek astronomy essentially adopted the older Babylonian system in the Hellenistic era, first introduced to Greece by Eudoxus of Cnidus in the 4th century BC.

During the 8th and 7th centuries BC, Babylonian astronomers developed a new approach to astronomy.

The Babylonian development of methods for predicting the motions of the planets is considered to be a major episode in the history of astronomy.

Babylonian astronomy served as the basis for much of Greek, classical Indian, Sassanian, Byzantine, Syrian, medieval Islamic, Central Asian, and Western European astronomy.

Logic was employed to some extent in Babylonian astronomy and medicine.

We do not know what these applications may have been, or whether there could have been any ; Babylonian astronomy, for example, truly flowered only later.

Astronomical models of the universe were proposed soon after astronomy began with the Babylonian astronomers, who viewed the universe as a flat disk floating in the ocean, and this forms the premise for early Greek maps like those of Anaximander and Hecataeus of Miletus.

In Babylonian astronomy, Vega may have been one of the stars named Dilgan, " the Messenger of Light ".

It is known to have been in use by the Roman era, based on concepts inherited by Hellenistic astronomy from Babylonian astronomy of the Chaldean period ( mid-1st millennium BC ), which, in turn, derived from an earlier system of lists of stars along the ecliptic.

The division of the ecliptic into the zodiacal signs originates in Babylonian (" Chaldean ") astronomy during the first half of the 1st millennium BC, likely during Median /" Neo-Babylonian " times ( 7th century BC ),

The Babylonian star catalogs entered Greek astronomy in the 4th century BC, via Eudoxus of Cnidus and others.

Among the sciences, astronomy and astrology still occupied a conspicuous place in Babylonian society.

Babylonian astronomy was the basis for much of what was done in Greek and Hellenistic astronomy, in classical Indian astronomy, in Sassanian, Byzantine and Syrian astronomy, in medieval Islamic astronomy, and in Central Asian and Western European astronomy.
