for the greater part of the first millennium BCE and tables made of both observed and predicted eclipses. While no table authored by Sudines has been found or is mentioned in other sources, the abundance of Babylonian tables that have survived suggests that they were an integral component of astronomical practice in this Mesopotamian culture. As a Babylonian, it is not unlikely that Sudines collaborated in the construction of astronomical tables. Moreover, other astronomers listed alongside Sudines have astronomical tables attributed to them that are not extant. Hipparchus, a foundational figure in Greek astronomy whose work became the basis for Ptolemy's Almagest, is credited as authoring a solar table that has not survived and has been the topic of much speculation. Sudines is also credited with a particular value for the length of the solar year. Neugebauer lists Sudines' solar year length as 365 1/4 γ' ε', which Rochberg interprets as 365 + 1/4 + 1/3 + 1/5, a value that she describes as making no astronomical sense. Valens references Sudines as a table author immediately after describing various values of year lengths, including two attributed separately to the Chaldeans and the Babylonians (Anthologies 9.12). Neither the Chaldean year length of 365 1/4 1/207 nor the Babylonian year length of 365 1/4 1/144 agrees with Sudines' value. In a 3rd century CE papyrus fragment containing a summary of a commentary on Plato's Timaeus, the Stoic philosopher Posidonius is listed as crediting Sudines with describing the planet Venus as the destroyer of women. Identifying planets as "destroyers" fits in to a larger discussion of the influences and Aristotelian qualities of the five planets, the sun, and the moon. Sudines' alleged participation in astrological as well as astronomical work fits in with Babylonian standards that did not explicitly differentiate between the two fields. References in Classical Sources Sudines is referenced in Greek and Latin texts as an expert on three topics: astrological knowledge, liver divination (hepatoscopy), and properties of stones and gems. Often he is listed alongside other known Babylonian astronomers. In addition to Sudines, Vettius Valens lists Kidenas, a Babylonian astronomer known from other references in Greek sources as well as the colophons of some Babylonian ephemerides. Valens also references Greek astronomers Hipparchus and Apollinarius who are both known to have iterated over Babylonian arithmetic methods and to have used Babylonian parameters and observations as integral parts of their astronomical theories.
