He was the delight of the family. His mother devoted herself to his education, and his father to his amusement. He made a puppet theatre for him, and, with two or three friends, drew the cords and acted plays to the boy's infinite delight. But a change soon came over this holiday life. His grandfather died, in 1712, from the effects of a cold, caught at an assembly. His extravagance had dissipated his fortune; and, from abundance and luxury, the family fell into the narrowest circumstances. The prospects of the father of Goldoni were dark. He had no employment and no profession, and his inherited property was all sold or mortgaged. In the midst of this distress, his wife gave birth to a son: this added to the solicitude of the father; but, unwilling to be the prey of useless gnawing cares, he set out on a visit to Rome, for the sake of diverting his thoughts. His wife remained at home with her sister, and two sons. The second, never a favourite, was put out to nurse; and she devoted herself to Carlo. He was gentle, obedient, and quiet. At the age of four he could read and write and say his catechism; on which they gave him a tutor. He grew to love books, and made progress in grammar, geography, and arithmetic; but the old instinct survived, and plays were his favourite reading. There were a good many in his father's library: he pored over them at his leisure hours, copied the passages that pleased him most; and, incited by a noble hardihood, at the age of eight, wrote a comedy. Some laughed at it; his mother scolded and kissed him at the same time; while others insisted that it was too clever to have been written by a child of his age, and that his tutor must have helped him.
Meanwhile his father, instead of returning after a short visit, remained four years at Rome. He had a rich friend there, who received him cordially, lodged him in his own house, and introduced him to Lancisi, physician and private attendant to Clement XI. He attached himself warmly to Goldoni, who was clever and agreeable, and sought to advance himself. Lancisi advised him to study medicine. The advice was taken. After attending lectures and hospitals for four years at Rome, he took his doctor's degree; and his patron sent him to Perugia to exercise his profession. He became in vogue in this town: if he were not the best physician in the world, he was an agreeable man, and quickly gained the esteem and friendship of the first families. Thus fortunately situated, he resolved to have his son with him. He does not appear to have thought of inviting his wife also; and the mother and child were separated, to the deep grief of the former. Carlo quitted Venice for the first time, in a felucca. He disembarked at the mouth of the Marecchia, and it was proposed that he should continue his journey on horseback. Carlo had never seen a horse except at a distance: he was frightened when placed on the saddle, confused when told to hold reins and whip; but, as the novelty wore off, he made acquaintance with this new and strange animal, and fed him with his own hands.
