His forehead showed symptoms of deep thought, and partially redeemed the somewhat mean effect of his other features.

The sharp nose, the thin lips, the cold grey eyes, the sallow sunken cheeks, were those of a precise, passionless, self-confident man, little likely to be led into any excess of love or hatred, but little likely also to be shaken in his resolve either for good or evil.

His face probably was a true index to his character.
Robespierre was not a cruel man; but he had none of that humanity, which makes the shedding of blood abominable to mankind, and which, had he possessed it, would have made his career impossible.
His hair was close curled in rolls upon his temples, and elaborately powdered.

The front and cuffs of his shirt were not only scrupulously clean, but starched and ironed with the most exact care.

He wore a blue coat, a white waistcoat, and knee-breeches.
