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.
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.
