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 Tetrarchy
The Herodian Tetrarchy was formed following the death of Herod the Great in 4 BCE, when his kingdom was divided between his sons Herod Archelaus as ethnarch, Herod Antipas and Philip as tetrarchs in inheritance, while Herod's sister Salome I shortly ruled a toparchy of Jamnia. Judea, the major section of the tetrarchy, was transformed by Rome in 6 CE, abolishing the rule of Herod Archelaus, thus forming the Province of Judea by joining together Judea proper, Samaria and Idumea. With the death of Salome I in 10 CE, her domain was also incorporated into the new Judea province. However, other parts of the Herodian Tetrarchy continued to function under Herodians. Thus, Philip the Tetrarch ruled Batanea, with Trachonitis, as well as Auranitis until 34 CE (his domain later being incorporated into the Province of Syria), while Herod Antipas ruled Galilee and Perea until 39 CE. The last notable Herodian ruler with some level of independence was Agrippa I, who was even granted lands of the Judea province, though with his death in 44 CE, the provincial status of Judea was restored for good.
