"Her sense of style is so laughably outdated it's nearly antediluvian."
Popularity Over Time
The antediluvian age is a symbolic line in the sand for the Abrahamic religions, including Judaism, Christianity, and Islam. According to the biblical Scriptures, Noah and his family constructed a giant wooden ark just prior to a 40-day flood, which wiped out every living thing save the creatures on the ark. Noah's family's return to dry land marked the paradigmatic end of the antediluvian age.
Did you Know?
The Latin construction of antediluvian means literally "before a flood," but in the 17th century the word was pressed into theological service to refer specifically to the time period before the biblical flood.
