II. Marcellus was practised in all forms of battle, but was especially skilful in single combat, so that he never declined any man's challenge, and slew all who challenged him. In Sicily he saved the life of his brother Otacilius when in great peril, by holding his shield over him and killing his assailants. For this conduct, young as he was, he received crowns[13] and rewards from the generals, and as he grew in reputation was elected _curule ædile_ by the people, and augur by the priests. This is a kind of priestly office, to which the law especially assigns the observance of auguries drawn from the flight of birds. During his tenure of the office of ædile, he was obliged, much against his will, to commence a law-suit. He had a son of his own name, in the bloom of youth, of great beauty, and equally with it admired by his countrymen for his modesty and education. Capitolinus, Marcellus's colleague, a licentious and reckless man, made disgraceful proposals to this lad. He first repelled his attacks alone, but on a second attempt told his father, and Marcellus, being much enraged, summoned the man before the Senate. He attempted many quibbles and subterfuges, and appealed to the tribunes of the people to support him, but as they refused his application he betook himself to pleading denial of the charge. There being no witnesses of what he had said, the Senate decided to send for the boy, and when they saw how he blushed and wept with a modesty mingled with unquenchable rage, they, without requiring any other proof, found Capitolinus guilty, and condemned him to pay a fine, with which Marcellus had silver libation vessels made, and consecrated them to the gods. III. After twenty-two years the first Punic War came to an end, and the Romans turned their attention to Gaulish troubles. The Insubrians, a Celtic tribe dwelling in Italy at the foot of the Alps, powerful by themselves, were collecting other forces, and enrolling all those Gauls who fought for hire, called Gæsatæ.
