Strabo, Geography

In ancient times, then, Dodona was under the rule of the Thesprotians; and so was Mount Tomarus,¹ or Tmarus (for it is called both ways), at the base of which the temple is situated. And both the tragic poets and Pindar have called Dodona “Thesprotian Dodona.” But later on it came under the rule of the Molossi. And it is after the Tomarus, people say, that those whom the poet calls interpreters of Zeus—whom he also calls “men with feet unwashen, men who sleep upon the ground”²—were called “tomouroi”; and in the Odyssey some so write the words of Amphinomus, when he counsels the wooers not to attack Telemachus until they inquire of Zeus: ““If the tomouroi of great Zeus approve, I myself shall slay, and I shall bid all the rest to aid, whereas if god averts it, I bid you stop.”
”³ For it is better, they argue, to write “tomouroi” than “themistes”; at any rate, nowhere in the poet are the oracles called “themistes,” but it is the decrees, statutes, and laws that are so called; and the people have been called “tomouroi” because “tomouroi” is a contraction of “tomarouroi,” the equivalent of “tomarophylakes.”⁴ Now although the more recent critics say “tomouroi,” yet in Homer one should interpret “themistes” (and also “boulai”) in a simpler way, though in a way that is a misuse of the term, as meaning those orders and decrees that are oracular, just as one also interprets “themistes” as meaning those that are made by law. For example, such is the case in the following: ““to give ear to the decree⁵ of Zeus from the oak-tree of lofty foliage.
