Farther Spain fell to his lot as quaestor

Farther Spain fell to his lot as quaestor; when there, as he was going the circuit of the province, by commission from the praetor, for the administration of justice, and had reached Gades, seeing a statue of Alexander the Great in the temple of Hercules, he sighed deeply, as if weary of his sluggish life, for having performed no memorable actions at an ages at which Alexander had already conquered the world. He, therefore, immediately sued for his discharge, with the view of embracing the first opportunity, which might present itself in The City, of entering upon a more exalted career. In the stillness of the night following, he dreamt that he lay with his own mother; but his confusion was relieved, and his hopes were raised to the highest pitch, by the interpreters of his dream, who expounded it as an omen that he should possess universal empire; for that the mother who in his sleep he had found submissive to his embraces, was no other than the earth, the common parent of all mankind.
