Are you sure of this? From everything I have read, Athenian juries were randomly selected from amidst the population, with legislation handled by the assembly. I do not see how the word senate really applies to them.
Basically, I thought the legislative body of Athens (called the Senate) also simply had a judicial function. I think that's what I taught my students, but I might have taught them wrongly and I might have forgotten what I taught them. :-) Anyone else? --LMS
Hm. I don't know anything about the period specifically after the thirty tyrants, but the general statement that democracy was restored suggests that legislation was passed the same way - by the assembly of all free men, not by a senate. I'm not even sure what the Athenian senate would refer to, except possibly the areopagus, who had an extremely reduced function. Some double-checking confirms Socrates was tried before a randomly selected jury, so what I'm going to do is change the statement unless someone provides evidence to the contrary, and add a few more details as well.
