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 architecture
Herodian architecture is a style of classical architecture characteristic of the numerous building projects undertaken during the reign (37–4 BC) of Herod the Great, the Roman client king of Judea. Herod undertook many colossal building projects, most famously his reconstruction of the Temple in Jerusalem (c. 19 BC). Many of his structures were built upon comparable, previous Hasmonean buildings and most of his have, in their turn, vanished as well.
