Cryptic (geology)
The Cryptic era is an informal term for the earliest geologic evolution of the Earth and Moon. It is the oldest (informal) era of the Hadean eon, and it is commonly accepted to have begun close to 4533 million (about 4.533 billion) years ago when the Earth and Moon formed. No samples exist to date the transition between the Cryptic era and the following Basin Groups era for the Moon (see also Pre-Nectarian), though sometimes it is stated that this era ended 4150 million years ago for one or both of these bodies. Neither this time period, nor any other Hadean subdivision, has been officially recognized by the International Commission on Stratigraphy.
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.
