Servius Maurus Honoratus
Servius Maurus Honoratus was a 4th century AD grammarian and commentator who states unequivocally that there were two locations referred to as the Columns or Pillars of Heracles; one at the Strait of Gibraltar leading to the Atlantic Ocean and the other at the Bosporus leading to the Black Sea. This was used by Eberhard Zangger to support his idea that Troy was Atlantis.
