Sostratus of Cnidus

Sostratus of Cnidus was a Greek architect and courtier of the early 3rd century BCE, credited with building the Pharos, the great lighthouse of Alexandria, under the first Ptolemaic kings. The lighthouse, counted among the Seven Wonders of the Ancient World, bore a dedication in his name. He also served the Ptolemies as a diplomat and was honoured with statues at Delphi and Delos.
