Tiberius and Caius Gracchus

Hence men like Drusus found fault with him because he bought silver dolphins at twelve hundred and fifty drachmas the pound. Again, their tempers were no less different than their speech. Tiberius was reasonable and gentle, while Caius was harsh and fiery, so that against his better judgment he was often carried away by anger as he spoke, raising his voice to a high pitch and uttering abuse and losing the thread of his discourse.
