affairs; in which, if there was occasion for secrecy, he wrote in cyphers; that is, he used the alphabet in such a manner, that not a single word could be made out. The way to decipher those epistles was to substitute the fourth for the first letter, as d for a, and so for the other letters respectively. Some things likewise pass under his name, said to have been written by him when a boy, or a very young man; as the Encomium of Hercules, a tragedy entitled Oedipus, and a collection of Apophthegms; all which Augustus forbad to be published, in a short and plain letter to Pompeius Macer, who was employed by him in the arrangement of his libraries. (38) LVII. He was perfect in the use of arms, an accomplished rider, and able to endure fatigue beyond all belief. On a march, he used to go at the head of his troops, sometimes on horseback, but oftener on foot, with his head bare in all kinds of weather. He would travel post in a light carriage [79] without baggage, at the rate of a hundred miles a day; and if he was stopped by floods in the rivers, he swam across, or floated on skins inflated with wind, so that he often anticipated intelligence of his movements. [80] LVIII. In his expeditions, it is difficult to say whether his caution or his daring was most conspicuous. He never marched his army by roads which were exposed to ambuscades, without having previously examined the nature of the ground by his scouts. Nor did he cross over to Britain, before he had carefully examined, in person [81], the navigation, the harbours, and the most convenient point of landing in the island. When intelligence was brought to him of the siege of his camp in Germany, he made his way to his troops, through the enemy’s stations, in a Gaulish dress. He crossed the sea from Brundisium and Dyrrachium, in the winter, through the midst of the enemy’s fleets; and the troops, under orders to join him, being slow in their movements, notwithstanding repeated messages to hurry them, but to no purpose, he at last went privately, and alone, aboard a small vessel in the night time, with his head muffled up; nor did he make himself known, or suffer the master to put about, although the wind blew strong against them, until they were ready to sink. LIX. He was never deterred from any enterprise, nor retarded in the prosecution of it, by superstition [82]. When a victim, which he was about to offer in sacrifice, made its (39) escape, he did not therefore defer his expedition against Scipio and Juba. And happening to fall, upon stepping out of the ship, he gave a lucky turn to the omen, by exclaiming, “I hold thee fast, Africa.” To chide the prophecies which were spread abroad, that the name of the Scipios was, by the decrees of fate, fortunate and invincible in that province, he retained in the camp a profligate wretch, of the family of the Cornelii, who, on account of his scandalous life, was surnamed Salutio.
