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.
Herodian dynasty
In 40 BCE, the Parthians invaded the eastern Roman provinces and managed to drive the Romans out of many areas. In Judea, the Hasmonean dynasty was restored under king Antigonus as a pro-Parthian monarch. Herod the Great, the son of Antipater the Idumean and Cypros (possibly of Nabataean descent), managed to escape to Rome. After convincing the Roman Senate of his sincere intentions in favor of Romans he eventually was announced as king of the Jews by the Roman Senate. Despite his announcement as king of the whole of Judea, Herod did not fully conquer it until 37 BCE. He subsequently ruled the Herodian kingdom as a vassal king for 34 years, crushing the opposition while also initiating huge building projects, including the harbor at Caesarea Maritima, the plaza surrounded by retaining walls at the Temple Mount, the Masada and the Herodium, among other fortresses and public works. Herod ruled Judea until 4 BCE; at his death his kingdom was divided among his three sons as a tetrarchy.
