TEMPLE WITH AN IRON STATUE SUSPENDED IN THE AIR BY LOADSTONE.
According to Pliny, Dinocrates built a temple at Alexandria, in honor of Arsinoe, sister and wife of Ptolemy Philadelphus. The whole interior was to have been incrusted with loadstone, in order that the statue of the princess, composed of iron, should be suspended in the centre, solely by magnetic influence. On the death of Ptolemy and of the architect, the idea was abandoned, and has never been executed elsewhere, though believed to be practicable. A similar fable was invented of the tomb of Mahomet.
