FOURTH TRIP 23 APRIL-16 JUNE 1624
Galileo was in poor health after his return to Florence in June 1616, and he blamed the city air. He began looking for a house outside the city, and in April 1617 he was able to rent the Villa Bellosguardo on the south side of the Arno, a lovely location from which he enjoyed an unobstructed view of the heavens above and a beautiful panorama of Florence at his feet. Galileo had three children from his common-law wife, the Venetian Marina Gamba, and he placed his two daughters in the neighboring convent of San Matteo in Arcetri, which he could reach in three-quarters of an hour on foot or by mule, when he was well enough to make the trip. His eldest daughter, Virginia, who had taken the name of Sister Maria Celeste, was an intelligent and warm-hearted woman who became a great comfort to her father. The younger sister, Livia, Sister Arcangela in religion, broke down under the strain of convent life and became chronically depressed. His son, Vincenzio, was legitimated by the grand duke and educated at the University of Pisa.
