Society for Interdisciplinary Studies
The Society for Interdisciplinary Studies (SIS) was founded in>1974 to promote discussion and further study of the ideas of Immanuel Velikovsky. He was one of the first to publicise the fact that the ancient chronology of Egypt was, and according to some, still is badly wrong. SIS is “the oldest and most up-to-date Society for information and research into cosmic catastrophes and ancient chronology revision.”
For its Jubilee Conference in 1999, P. John Crowe delivered a lengthy paper(e) on the various attempts to revise ancient chronology, before and after Velikovsky.<
Trevor Palmer who was Chairman of the SIS from 1995-1998 and 2000-2002 has written Perilous Planet Earth, which is a comprehensive history of catastrophism and includes a couple of chapters on Atlantis.
In 1997, the SIS organised a conference entitled Natural Catastrophes During Bronze Age Civilisations: Archaeological, geological, astronomical and cultural perspectives. The background to the conference is worth a read.(c)
A search on their website(a) reveals a number of articles and reviews relating to Atlantis – not all positive. Their Catastrophism CD(b), although expensive, is an absolute must for any serious student of the subject.
S.I.S. has also compiled a valuable collection of web resources on its website(d).
