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.
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.
