Sostratos, architect of the famous light-house on the Island of Pharos, Alexandria, once numbered among the seven wonders of the world, engraved deeply on one of the stones the words, ‘Sostratos of Gnidos, son of Dexiphanos, to the Gods protecting those on the sea.’ Knowing very well that Ptolemy, his employer, would not be satisfied with this inscription, he covered it with a thin coating of plaster on which he inscribed the name of Ptolemy. In time the plaster disappeared, and with it the name of the king, so that in the end the architect had all the credit for the work.
