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.
Timarion
The Timarion () is a Byzantine pseudo-Lucianic satirical dialogue probably composed in the twelfth century (there are references to the eleventh-century Michael Psellus), though possibly later. The eponymous hero, on his way to a Christian fair at Thessalonica, is unexpectedly taken to Hades, which is ruled by pagan figures and pagan justice, and where "Galilæans" (that is, Christians) make up only one sect (αἵρεσις) of many.
