The Essene's sister sect in Egypt: another medical site?

The Essenes were, allegedly, the authors of the Dead Sea Scrolls and were settled by the Dead Sea. An ancient source locates their sister sect, The 'Therapeutae', as being by the shores of Lake Mareotis in Egypt. No scholar has previously sought to locate where exactly on Lake Mareotis they were settled. Using clues from Essene sites around the Dead Sea, an attempt is made to suggest a specific location for the Therapeutae. Since there are signs of medical activity at many of the Essene sites, a site with medical association is also sought for the location of the Essene's sister sect in Egypt. A suitable site is found at Canopus.
