Question 5. Who were the Χρηστοί among the Arcadians and Lacedaemonians?
Solution. When the Lacedaemonians were agreed with the Tegeats, they made a league with them, and set up a common pillar on the river Alpheus, upon which this is written, among other things, Drive out the Messenians from your borders, and make none of them χρηστοί, good. Aristotle interpreting this saith, that none of the Tegeats ought to be slain that endeavored to bring aid to the Lacedaemonians.
Question 6. Who is Κριθολόγος among the Opuntians?
Solution. The most of the Greeks did use barley at their ancient sacrifices, when the citizens offered their first-fruits; now they called him Crithologus who presided over the sacrifices and received the first-fruits. They had two priests, one that had the chief charge of the divine things, the other of daemnonic affairs.
