Grammatopoulos http://executableknowledge.com/2008/03/21/aegean-sea-by-c-grammatopoulos/ http://executableknowledge.com/2008/03/21/aegean-sea-by-c-grammatopoulos/#comments Fri, 21 Mar 2008 07:48:04 +0000 George Tsintsifas http://executableknowledge.com/2008/03/21/aegean-sea-by-c-grammatopoulos/ Greek Mythology. Aegeus, king of Athens and father of Theseus, falls into the sea after he saw Theseaus’s boat. They had prearranged that if Theseus would die, the ship would come back wearing black sails. Theseus did not die but forgot to change the sails to white. So, Aegeus died in vain.

about to John’s matrix.
