In the prosecution of this dangerous enterprise, Gabinius relied strongly on the assistance of a very remarkable man, then his second in command, who afterward acted a very important part in the subsequent history of Cleopatra. His name was Mark Antony. Antony was born in Rome, of a very distinguished family, but his father died when he was very young, and being left subsequently much to himself, he became a very wild and dissolute young man. He wasted the property which his father had left him in folly and vice; and then going on desperately in the same career, he soon incurred enormous debts, and involved himself, in consequence, in inextricable difficulties. His creditors continually harassed him with importunities for money, and with suits at law to compel payments which he had no means of making. He was likewise incessantly pursued by the hostility of the many enemies that he had made in the city by his violence and his crimes. At length he absconded, and went to Greece. Here Gabinius, when on his way to Syria, met him, and invited him to join his army rather than to remain where he was in idleness and destitution. Antony, who was as proud and lofty in spirit as he was degraded in morals and condition, refused to do this unless Gabinius would give him a command. Gabinius saw in the daring and reckless energy which Antony manifested the indications of the class of qualities which in those days made a successful soldier, and acceded to his terms. He gave him the command of his cavalry. Antony distinguished himself in the Syrian campaigns that followed, and was now full of eagerness to engage in this Egyptian enterprise. In fact, it was mainly his zeal and enthusiasm to embark in the undertaking which was the means of deciding Gabinius to consent to Ptolemy's proposals. The danger and difficulty which they considered as most to be apprehended in the whole expedition was the getting across the desert to Pelusium. In fact, the great protection of Egypt had always been her isolation. The trackless and desolate sands, being wholly destitute of water, and utterly void, could be traversed, even by a caravan of peaceful travelers, only with great difficulty and danger. For an army to attempt to cross them, exposed, as the troops would necessarily be, to the assaults of enemies who might advance to meet them on the way, and sure of encountering a terrible opposition from fresh and vigorous bands when they should arrive--wayworn and exhausted by the physical hardships of the way--at the borders of the inhabited country, was a desperate undertaking. Many instances occurred in ancient times in which vast bodies of troops, in attempting marches over the deserts by which Egypt was surrounded, were wholly destroyed by famine or thirst, or overwhelmed by storms of sand.
