Alexandros Angelis (1978- ) is the Greek author of Our Unknown Ancient Past . He has published a lengthy article on Graham Hancock‘s website(a) in which he reprises elements from his book; ancient technology, Greeks in Polynesia, Hyperboreans and of course, Atlantis.
His book has a lot of material relating to Atlantis as does his website(b). Angelis has opted for the Azores as part of Plato’s Atlantis(c).
There are several matters raised by Angelis that I cannot agree with, particularly his suggestion that the ending of the Younger Dryas and Plato’s date for the inundation of Atlantis is too much of a coincidence not to be connected(d)! I contend that there is no coincidence as Atlantis (or Athens) did not exist until many millennia after the Younger Dryas. I have dealt with this in the Dating Atlantis entry and more fully in Joining the Dots.
