Seneca · On the blush of modesty
Letters 11.4
Sulla, when the blood mantled his cheeks, was in his fiercest mood. Pompey had the most sensitive cast of countenance; he always blushed in the presence of a gathering, and especially at a public assembly. Fabianus also, I remember, reddened when he appeared as a witness before the senate; and his embarrassment became him to a remarkable degree.
