Aulus Cornelius Celsus

Live in rooms full of light. Avoid heavy food. Be moderate in the drinking of wine. Take massage, baths, exercise, and gymnastics. Fight insomnia with gentle rocking or the sound of running water. Change surroundings and take long journeys. Strictly avoid frightening ideas. Indulge in cheerful conversation and amusements. Listen to music.

This is one of their [the Christians'] rules. Let no man that is learned, wise, or prudent come among us: but if they be unlearned, or a child, or an idiot, let him freely come. So they openly declare that none but the ignorant, and those devoid of understanding, slaves, women, and children, are fit disciples for the God they worship.
