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.
Athena (Saint Seiya)
Masami Kurumada revealed in volume 1 of "Saint Seiya" that Athena had battled in the age of myth against the Giants, Ares and Poseidon, each in incarnations centuries apart. He also revealed later that she has battled Hades in the age of myth, then in the fifteenth century, eighteenth century and finally in the twentieth century. She battled Poseidon in the twentieth century, 2000 years after their battle in the region of Attica.
