Italian Early Renaissance Painter, ca.1455-1508 Painter and illuminator, half-brother of Cristoforo de Predis. He began his career as an illuminator, working with Cristoforo. His first documented works are seven miniatures for a Book of Hours (1472; destr.) for Vitaliano Borromeo (1451-95) and a Book of Hours for Francesco Borromeo. He was paid for the latter in 1474, and the codex can probably be identified with the Horae Beatae Virginis Mariae (ex-H. P. Kraus, New York, 1987; Suida, 1959). From 1479 he artist worked in the Milanese mint, together with his brother Bernardino. For some years Giovanni Ambrogio also worked at the court of Ludovico Sforza ('il Moro'), especially as a portrait painter. This is borne out by the charcoal drawing of Bianca Maria Sforza (1492; Venice, Accad.), which dates from a period before her marriage to Emperor Maximilian I. The portrait was ordered by her future husband, through Frederick III, Duke of Saxony, to give him an idea of her appearance. It was favourably received, and later a painting of the same subject (Washington, DC, N.G.A.) was commissioned from Giovanni Ambrogio.   Related Paintings of PREDIS, Ambrogio de :. | Portrat of a young man | Portrait of a Man | Portrait of a Young Man sgt | Portrait of a Woman age | Portrait of a lady |

William Morris Davis
February 12, 1850 - February 5, 1934,Davis, who was born in Philadelphia, Pennsylvania, was educated at Harvard. He returned to teach there in 1877 after a period as a meteorologist in Argentina and as an assistant with the North Pacific Survey. He became professor of physical geography in 1890 and of geology in 1898. Davis is acknowledged as the founder of geomorphology, the study of landforms. In his The Rivers and Valleys of Pennsylvania (1889) he first introduced what later became known as the Davisian systems of landscape analysis. His aim was to provide an explanatory description of how landforms change in an ideal situation and his most important contribution to this was his introduction of the cycle of erosion into geographical thought. He proposed a complete cycle of youth, maturity, and old age to describe the evolution of a landscape. In youth rivers occupy steep V-shaped valleys while in old age the valleys are broad. The end product would be a flat featureless plain he called a epeneplaine. This was an ideal cycle but in practice the cycle would invariably be interrupted by Earth movements. It was, nevertheless, strongly attacked by German geographers who objected to it on the grounds that it neglected such vital factors as weathering and climate in transforming the landscape. They also believed him to be undermining their argument that landforms could only be discovered by local fieldwork and the production of regional monographs. Davis also produced an influential work,
