At first the coffin was of pure gold, but this having led to a violation of the tomb, it was replaced by one of alabaster.

But not these, not even the great light-house, Pharos, built of blocks of white marble and so high that the fire continually burning on its top could be seen many miles off at sea--the Pharos counted as one of the seven wonders of the world--it is not these magnificent achievements of architecture that arrest our attention; the true, the most glorious monument of the Macedonian kings of Egypt is the Museum.
Its influences will last when even the Pyramids have passed away.
THE ALEXANDRIAN MUSEUM.

The Alexandrian Museum was commenced by Ptolemy Soter, and was completed by his son Ptolemy Philadelphus.

It was situated in the Bruchion, the aristocratic quarter of the city, adjoining the king's palace.

Built of marble, it was surrounded with a piazza, in which the residents might walk and converse together.
