Hadean
The Hadean () is a geologic eon of the Earth pre-dating the Archean. It began with the formation of the Earth about 4.6 billion years ago and ended, as defined by the ICS, 4 billion years ago. , the ICS describes its status as ""informal"". Geologist Preston Cloud coined the term in 1972, originally to label the period before the earliest-known rocks on Earth. W. Brian Harland later coined an almost synonymous term, the "Priscoan period", from "priscus", the Latin word for "ancient". Other, older texts simply refer to the eon as the Pre-Archean.
Seder Olam Zutta
With the deaths of Haggai, Zechariah, and Malachi—more exactly, in the 52nd year of the Persian domination, or year 3442 of the creation—prophecy ceased and the period of the wise men ("ḥakamim") began. From Hananiah (Zerubbabel's grandson) onward every exilarch is indicated as having been guided by wise men. The names of the kings that reigned over Judea from Alexander the Great to Roman Palaestina during the destruction of the Second Temple are given. Like the "Seder 'Olam Rabbah", this chronicle gives the reigns of the Maccabees and the Herods as covering 103 years each. The Herodian dynasty consisted, according to the "Seder 'Olam Zuṭa", of three kings only—Herod, Agrippa, and Monobaz; at the end of Monobaz's reign and during the time of the 11th exilarch, Shechaniah, the son of Shemaiah, the Romans destroyed the Temple. Further, from Nahum, the 17th exilarch, the names are given of the wise men, probably the chiefs of the academy, who assisted the exilarchs. With Rab Huna, 29th exilarch, the direct male line of descent from David terminated. The exilarchs following are stated to have been descendants of Rab Huna through his daughter, the wife of R. Hananiah, the head of the yeshibah, whose marriage is related at length.
