Book 8
10.8
But the Arcadians got in their rear unperceived, and the Lacedaemonians were surrounded, losing the greater part of their army, while King Agis himself fell, the son of Eudamidas. The Mantineans affirmed that Poseidon too manifested himself in their defence, and for this reason they erected a trophy as an offering to Poseidon.
10.9
That gods were present at war and slaughter of men has been told by the poets who have treated of the sufferings of heroes at Troy, and the Athenians relate in song how gods sided with them at Marathon and at the battle of Salamis. Very plainly the host of the Gauls was destroyed at Delphi by the god, and manifestly by demons. So there is precedent for the story of the Mantineans that they won their victory by the aid of Poseidon.
10.10
Arcesilaus, an ancestor, ninth in descent, of' Leocydes, who with Lydiades was general of the Megalopolitans, is said by the Arcadians to have seen, when dwelling in Lycosura, the sacred deer, enfeebled with age, of the goddess called Lady. This deer, they say, had a collar round its neck, with writing on the collar:—I was a fawn when captured, at the time when Agapenor went to Troy.This story proves that the deer is an animal much longer-lived even than the elephant.
11.1
After the sanctuary of Poseidon you will come to a place full of oak trees, called Sea, and the road from Mantineia to Tegea leads through the oaks. The boundary between Mantineia and Tegea is the round altar on the highroad. If you will turn aside to the left from the sanctuary of Poseidon, you will reach, after going just about five stades, the graves of the daughters of Pelias. These, the Mantineans say, came to live with them when they were fleeing from the scandal at their father's death.
