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.
Assyrian Neo-Aramaic
Aramaic was the language of commerce, trade and communication and became the vernacular language of Assyria in the late Iron Age and classical antiquity. It became the lingua franca of the Neo-Assyrian Empire (911–605 BC), Neo-Babylonian Empire (605–539 BC), the Achaemenid Empire (539–323 BC), the Parthian Empire (247 BC–224 AD), and the Sasanian Empire (224–651 AD). Aramaic writing has been found as far north as Hadrians Wall in Ancient Britain, in the form of inscriptions in Aramaic, made by Assyrian and Aramean soldiers serving in the Roman Legions in northern England during the 2ndcentury AD.
