AKA Abderite
A native of Abdera, a maritime city of Thrace. The Abderitans were proverbial for stupidity, hence the phrase, "You have no more mind than an Abderite." (Needless to say, this insult did not last through the centuries).
Despite the bad press, the city gave birth to some of the wisest men of Greece: Democritos (the laughing philosopher), Protagoras (the great sophist), Anaxarchos (the philosopher and friend of Alexander), Hecatæos (the historian).
