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.
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.
