These are instructive remains, indicating the ideas of the Greeks respecting fortification in the time of Epaminondas. It appears that Mantinea was not so large as Tegea, to which last Curtius assigns a circumference of more than three miles (p. 253).

[439] It seems, however, doubtful whether there were not some common Arcadian coins struck, even before the battle of Leuktra.
Some such are extant; but they are referred by K. O. Müller, as well as by M. Boeckh (Metrologisch. Untersuchungen, p. 92) to a later date subsequent to the foundation of Megalopolis.
On the other hand, Ernst Curtius (Beyträge zur Aeltern Münzkunde, p. 85-90, Berlin, 1851) contends that there is a great difference in the style and execution of these coins, and that several in all probability belong to a date earlier than the battle of Leuktra. He supposes that these older coins were struck in connection with the Pan-Arcadian sanctuary and temple of Zeus Lykæus, and probably out of a common treasury at the temple of that god for religious purposes; perhaps also in connection with the temple of Artemis Hymnia (Pausan. viii, 5, 11) between Mantinea and Orchomenus.
