The Biblical flood prepares to leave the antediluvian world,
Jacopo Bassano and assistants, 1579 In the
Christian Bible,
Hebrew Torah and
Islamic Quran, the antediluvian period begins with the Fall of the first man and woman, according to
Genesis and ends with the destruction of all life on the earth except those saved with
Noah in the
ark (Noah and his wife, his three sons and their wives). According to Bishop
Ussher's 17th-century
chronology, the antediluvian period lasted for 1656 years, from Creation (some say the fall of man) at 4004 BC to the Flood at 2348 BC. The elements of the narrative include some of the best-known stories in the Bible – the creation,
Adam and Eve, and
Cain and Abel, followed by the genealogies tracing the descendants of Cain and
Seth, the third mentioned son of Adam and Eve. (These genealogies provide the framework for the biblical chronology, in the form "A lived X years and begat B".) The Bible speaks of this era as being a time of great wickedness. There were
Gibborim (giants) in the earth in those days as well as
Nephilim; some
Bible translations identify the two as one and the same. The Gibborim were unusually powerful; Genesis calls them "mighty men which were of old, men of renown". The antediluvian period ended when God sent the Flood to wipe out all life except Noah, his family, and the animals they took with them. Nevertheless, the Nephilim (literally meaning 'fallen ones', from the Hebrew root n-f-l 'to fall') reappear much later in the biblical narrative, in
Numbers (where the spies sent forth by
Moses report that there were Nephilim or "giants" in the
Promised Land).
In early geology of "Secondary rock",
Lyme Regis , 1829 Early scientific attempts at reconstructing the
history of the Earth were founded on the biblical narrative and thus used the term
antediluvian to refer to a period understood to be essentially similar to the biblical one. Early scientific interpretation of the biblical narrative divided the antediluvian into sub-periods based on the
six days of Creation: • Pre-Adamitic (the first 5 days, Gen 1:1 to Gen 2:3) • Primary (the formation of the physical universe and the earth) • Secondary (creation of plants and animals) • Adamitic (or Tertiary, from the Creation of man to the
Great Flood; Gen 2:5 to Gen 7:8), corresponding to
St. Augustine's First Age of his
Six Ages of the World Prior to the 19th century, rock was classified into three main types: primary or primitive (
igneous and
metamorphic rock), secondary (
sedimentary rock) and tertiary (
sediments). The primary rocks (like
granite and
gneiss) are void of fossils and were thought to be associated with the very creation of the world in the primary Pre-Adamitic period. The secondary rocks, often containing copious fossils, though human remains had not been found, were thought to have been laid down in the secondary Pre-Adamitic period. The Tertiary rocks (sediments) were thought to have been put down after Creation and possibly in connection to a flood event, and were thus associated with the Adamitic period. The Post-Flood period was termed the
Quaternary, a name still in use in geology. As mapping of the geological
strata progressed in the early decades of the 19th century, the estimated lengths of the various sub-periods were greatly increased. The fossil rich Secondary Pre-Adamitic period was divided up into the
Coal period, the
Lias and the
Chalk period, later expanded into the now-familiar
geologic time scale of the
Phanerozoic. The term
antediluvian was used in
natural science well into the 19th century and lingered in popular imagination despite increasingly detailed
stratigraphy mapping the
Earth's past, and was often used for the
Pleistocene period, where
humans existed alongside now extinct
megafauna. ==The antediluvian world==
