Note 246 — Chapter III · THE WORKS OF ÆSCHYLUS
Reading edition
The actual rule of the Areopagite Court was that if the votes were even the defendant was acquitted. This rule was explained as derived from the “Vote of Athena” in the trial of Orestes. It seems then that Athena’s vote here makes inequality, not equality. Therefore her pebble is not put into either urn, but laid between them.
