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.
History of Hungary
The Iron Age commenced around 800 BC, associated with "Thraco-Cimmerian" artefact types, 
representing the overlap of the pre-Scythian (Novocherkassk culture) and pre-Celtic (Hallstatt culture) cultural spheres.
Hallstatt occupation of western Transdanubia is evident from about 750 BC Early Greek ethnography locates the Agathyrsi and the Sigynnae in the region.
By the 4th century BC, the Pannonian basin was occupied by Pannonians (assumed to be an Illyrian tribal confederation) and by Celts (Taurisci). Following 279 BC, the Celtic Scordisci after their defeat at Delphi, settled in southern Transdanubia. The northeastern part of the Carpathian basin was reached by the Boii in the 2nd century BC.
