“It is seldom,” says Velleius, “that men who have arrived at eminence, have not had powerful coadjutors in steering the course of their fortunes; thus the two Scipios had the two Lælii, whom they set in every respect on a level with themselves; thus the emperor Augustus had Marcus Agrippa, and after him Statilius Taurus. The newness of these men’s families proved no obstruction to their attainment of many consulships and triumphs, and of sacerdotal offices in great numbers. For great affairs demand great co-operators (in small matters, the smallness of assistance does not mar the proceedings), and it is for the interest of the public, that what is necessary for business should be eminent in dignity, and that usefulness should be fortified with influence. In conformity with these examples, Tiberius Cæsar has had, and still has, Ælius Sejanus, a most excellent coadjutor in all the toils of government, a man whose father was chief of the equestrian order, and who, on his mother’s side is connected with some of the most illustrious and ancient families, ennobled by high preferments; who has brothers, cousins, and an uncle, of consular rank; who is remarkable for fidelity in the discharge of his duties, and for ability to endure fatigue, the constitution of his body corresponding with the vigour of his mind; a man of pleasing gravity, and of unaffected cheerfulness; appearing, in the despatch of business, like a man quite at ease; assuming nothing to himself, and hence receiving every honour; always deeming himself inferior to other men’s estimation of him; calm in looks and conversation, but in mind indefatigably vigilant.
