Of course, the glory of erecting such an edifice as the Pharos of Alexandria, and of maintaining it in the performance of its functions, was very great; the question might, however, very naturally arise whether this glory was justly due to the architect through whose scientific skill the work was actually accomplished, or to the monarch by whose power and resources the architect was sustained. The name of the architect was Sostratus. He was a Greek. The monarch was, as has already been stated, the second Ptolemy, called commonly Ptolemy Philadelphus. Ptolemy ordered that, in completing the tower, a marble tablet should be built into the wall, at a suitable place near the summit, and that a proper inscription should be carved upon it, with his name as the builder of the edifice conspicuous thereon. Sostratus preferred inserting his own name. He accordingly made the tablet and set it in its place. He cut the inscription upon the face of it, in Greek characters, with his own name as the author of the work. He did this secretly, and then covered the face of the tablet with an artificial composition, made with lime, to imitate the natural surface of the stone. On this outer surface he cut a new inscription, in which he inserted the name of the king. In process of time the lime moldered away, the king's inscription disappeared, and his own, which thenceforward continued as long as the building endured, came out to view. The Pharos was said to have been four hundred feet high. It was famed throughout the world for many centuries; nothing, however, remains of it now but a heap of useless and unmeaning ruins.
