the end of the Classic period and presages this and other developments of Hellenistic architecture, such as the slenderness (a height of 6.34 column diameters) of the Doric columns of the exterior. The site around the temple has been excavated in annual campaigns since 1973: the great open-air altar, baths, and ancient accommodations for visitors have been unearthed. The temple stands on the site of an Archaic period temple, of which only a foundation wall is still visible. The stadion has recently been discovered. It is notable for its well-preserved vaulted entrance tunnel, dated to about 320 BC, with ancient graffiti on the walls. The material discovered in the excavations is on display in an on-site museum constructed as a part of the University of California's excavations. In 2018, archaeologists discovered a large, intact tomb dating to the early Mycenaean era (1650–1400 B.C.). The Battle of the Nemea River In 394 BC the Battle of the Nemea River was fought between Sparta and her Achaian, Elean, Mantinean, and the Tegeate allies against a coalition of Boeotians, Euboeans, Athenians, Corinthians, and Argives. This was to be the last clear-cut victory that Sparta enjoyed. The tactics were similar to all other Greek hoplite battles, except that when the armies were arrayed, with the Spartans having the customary honour of being on the right, the army drifted right as it advanced. This was not good for the Spartan allies, as it exposed the soldiers to a flanking attack, but it gave the Spartans the opportunity to use their superior coordination and discipline to roll up the flank of the Athenians, who were stationed opposite. The result of the battle was a victory for Sparta, even though her allies on the left suffered significant losses. This willingness to accept losses on the left flank for flanking position on the right was a dramatic change from typical conservative hoplite military tactics.
