XX. Among the other liberal arts which he was taught in his youth, he was instructed in music; and immediately after (350) his advancement to the empire, he sent for Terpnus, a performer upon the harp [582], who flourished at that time with the highest reputation. Sitting with him for several days following, as he sang and played after supper, until late at night, he began by degrees to practise upon the instrument himself. Nor did he omit any of those expedients which artists in music adopt, for the preservation and improvement of their voices. He would lie upon his back with a sheet of lead upon his breast, clear his stomach and bowels by vomits and clysters, and forbear the eating of fruits, or food prejudicial to the voice. Encouraged by his proficiency, though his voice was naturally neither loud nor clear, he was desirous of appearing upon the stage, frequently repeating amongst his friends a Greek proverb to this effect: "that no one had any regard for music which they never heard." Accordingly, he made his first public appearance at Naples; and although the theatre quivered with the sudden shock of an earthquake, he did not desist, until he had finished the piece of music he had begun. He played and sung in the same place several times, and for several days together; taking only now and then a little respite to refresh his voice. Impatient of retirement, it was his custom to go from the bath to the theatre; and after dining in the orchestra, amidst a crowded assembly of the people, he promised them in Greek [583], "that after he had drank a little, he would give them a tune which would make their ears tingle." Being highly pleased with the songs that were sung in his praise by some Alexandrians belonging to the fleet just arrived at Naples [584], he sent for more of the like singers from Alexandria. At the same time, he chose young men of the equestrian order, and above five thousand robust young fellows from the common people, on purpose to learn various kinds of applause, called bombi, imbrices, and testae [585], which they were to practise in his favour, whenever he performed. They were (351) divided into several parties, and were remarkable for their fine heads of hair, and were extremely well dressed, with rings upon their left hands. The leaders of these bands had salaries of forty thousand sesterces allowed them.
