The French Catholic Historian and writer Fernand Crombette wrote about Atlantis and he places its civilization after the flood. He actually places its destruction on the same date as the parting of the red sea. He theorizes that the effects of the red sea parting had other catastrophic effects around the earth such as coastal flooding and the sinking of Atlantis.
Hear is a website discussing his life and work:

There is a book discussing his life work in English called: If the World Only knew! I highly recommend it. He discusses the fact that the earth at the time of Christ was about 4000 years old and proves it through a unique way of translating Egyptian Hieroglyphs and Sumerian Cuneiform. His translations line up exactly with the biblical timeline. I will try to find more internet material on this great Catholic Historian. Alas, most of his many books are in French.
