Two large pyramidal columns set up by the Phœnicians as lighthouses and landmarks, dedicated, one to Herculēs (the sun), and the other to Astartē (the moon).
By the Greeks and Romans the two pyramidal mountains at the Straits of Gibraltar (Calpē and Aby̆la), the former in Europe and the latter in Africa, were termed the Pillars of Herculēs.
