**ANÆDEIA**, in antiquity, a denomination given to a silver stool placed in the Arcopagus, on which the defendant, or person accused, was seated for examination. The word is Greek, ἀναδίνειν, which imports impudence; but, according to Junius's correction, it should rather be ἀναδίνειν, q.d. innocence. The plaintiff, or accuser, was placed on an opposite stool called ἀναδίνειν, or injury; here he propounded three questions to the party accused, to which positive answers were to be given. The first, Are you guilty of this fact? The second, How did you commit the fact? The third, Who were your accomplices?

**ANÆSTHESIA**, signifies a privation of the senses.
