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.
Harran
A few kilometers from the village of Altınbaşak are the archaeological remains of ancient Harran, a major commercial, cultural, and religious center first inhabited in the Early Bronze Age III (3rd millennium BCE) period. It was known as Ḫarrānu in the Assyrian period; Paddan-Aram/"Ḫaran, transliterated as Charan" () from the Hebrew Bible; Charran/Kharan from Armenian texts, Carrhae () under the Roman and Byzantine empires; Hellenopolis ( meaning 'Greek city') in the Early Christian period; and Ḥarrān () in the Islamic period. It is mentioned, in Movses Khorenatsi's and Mikayel Chamchian's History of Armenia, as being under the authority of prince Sanadroug of Armenia, the sovereignty of which he assigned to Queen Helena of Adiabene.
