The inside of the citadel was adorned with a multitude of edifices. The flat space on the rock of the Acropolis is not more than eight hundred feet in length, and about four hundred feet in breadth,--a small extent for the site of the primitive city of the Athenians; but an area of great size, when considered as the base only of temples and marble palaces, containing not a single structure which might not be denominated a masterpiece of art[57]. The most remarkable of these were a magnificent temple of Minerva, styled Parthenon, because that goddess was a virgin--this the Persians destroyed, out it was rebuilt with still greater splendour by Pericles--the temple of Neptune and Minerva jointly; a temple dedicated to Victory, adorned with paintings, principally the work of Polygnotus, and constructed of white marble. Within the citadel, also, was an immense number of statues, erected by religion and gratitude, on which the chisels of Myron, Phidias, Alcamenes, and other artists of renown, seemed to have bestowed animation. Of these statues, some were those of famous Athenian generals; such as Pericles, Phormio, Iphicrates, and Timotheus; and others, those of the gods. It appears surprising that so many temples should have been crowded together within the narrow compass of the Athenian Acropolis; but the Roman Capitol, though not much more spacious, contained at least thirty temples[58]. "In its pride and glory," says Chandler, "the Acropolis appeared as one entire offering to the deity, surpassing in excellence, and astonishing in richness. Heliodorus employed on it fifteen books. The curiosities of various kinds, with the pictures, statues, and pieces of sculpture, were so many and so remarkable, as to supply Polemo Periegetes with matter for four volumes; and Strabo affirms, that as many more would be required in treating of Athens and of Attica. As the stranger draws near to the present entrance of the citadel, he passes before the façade of the Propylea; the old entrance to the Acropolis, between its Doric pillars, being walled up. Pausanias says, "There is only one entrance to the Acropolis of Athens; it being in every remaining part of its circuit a precipice, and fortified by strong walls. This entrance was fronted by a magnificent building, called the Propylea, covered with roofs of white marble, which surpassed, for beauty and the dimensions of the marble, all that I have seen." This is now in ruins. This was the most expensive work undertaken by Pericles, and is said to have cost 2,500 talents (£452,700). It took five years in building, and was completed B.C. 437.
