I love lighthouses...

Theon remembered the night when Zoë and he arrived at Alexandria by sailing ship from Sparta. It had been stormy on the approach with wind, rain and waves hurling cold salt water against their faces. Zoë was great with child and nauseous. Both of them were tired and sore afraid. Theon remembered seeing the light of the Pharos that night. It seemed as bright as the sun; a safe beacon for weary sailors. Zoë remarked that the baby was kicking in her womb as they passed the statue of Isis sitting in front of the lighthouse with a lion at her feet.

The Greek architect Sostrades designed the Pharos lighthouse as three towers one on top of each other, standing on a massive base two storeys high. The first tower had twenty storeys and housed the lighthouse staff; a division of soldiers and many slaves. The second tower was ten storeys high with a spiral walkway for horses and oxen carrying logs up to the tower above. The third tower was seven storeys high. On top of this were the fire and bronze mirror. The beam of light from the mirror could be seen from as far away as seventy sea miles from the island. At the very crown of the lighthouse was a statue of Poseidon, god of the sea. The lighthouse stood on the eastern side of the island of Pharos, with the temple of Poseidon at its western extremity. A half-mile long causeway, the Heptastadion, connected the Pharos and the mainland. Isis was the protective deity of the port and its lighthouse lay in her aspect as Isis-Pharia, the protector of mariners.
