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,  Related Paintings of William Morris Davis :. | Details of The Burial of Count Orgaz | The Palazzo Dario | plafond veritas-pulchritudo-bonitas | Banks of the Seine w tih Pont de Clichy in thte Spring (nn04) | Field of Irses at Giverny |

Mattia Preti
1613-1699 Italian Mattia Preti Gallery Born in the small town of Taverna in Calabria, Preti was sometimes called Il Cavalier Calabrese (the Knight of Calabria). His early apprenticeship is said to have been with the "Caravaggist" Giovanni Battista Caracciolo, which may account for his life-long interest in the style of Caravaggio. Probably before 1630, Preti joined his brother Gregorio (also a painter), in Rome, where he became familiar with the techniques of Caravaggio and his school as well as with the work of Guercino, Rubens, Reni, Giovanni Lanfranco. In Rome, he painted fresco cycles in Sant'Andrea della Valle and San Carlo ai Catinari. Between 1644 and 1646, he may have spent time in Venice, but remained based in Rome until 1653, returning later in 1660-61. He painted frescoes for the church of San Biago at Modena (app. 1651-2) and participated in the fresco decoration of the Palazzo Pamphilj in Valmontone (documented 1660-61), where he worked along with Pier Francesco Mola, Gaspar Dughet, Francesco Cozza, Giovanni Battista Tassi (il Cortonese), and Guglielmo Cortese.

Whitfield Fine Art Gallery, London.During most of 1653-1660, he worked in Naples, where he was influenced by the other major Neapolitan painter of his era, Luca Giordano. One of Preti's masterpieces were a series of large frescoes, ex-votos of the plague (which were painted on seven city gates but have since been lost to the ravages of time), depicting the Virgin or saints delivering people from the plague. Two sketches are in the Capodimonte Museum in Naples. The bozzetto of the Virgin with the baby Jesus looming over the dying and their burial parties envisions a Last Judgement presided over by a woman. Preti's salary for the work was 1500 ducats. Preti also won a commission to supervise the construction, carving, and gilding for the nave and transept of San Pietro a Maiella. Having been made a Knight of Grace in the Order of St John, he visited the order??s headquarters in Malta in 1659 and spent most of the remainder of his life there. Preti transformed the interior of St. John's Co-Cathedral in Valletta, with a huge series of paintings on the life and martyrdom of St. John the Baptist (1661-1666). In Malta one also can find many paintings of Preti in private collections and in parish churches. His increased reputation led to an expanded circle of patrons, and he received commissions from all over Europe. Preti was fortunate to enjoy a long career and have a considerable artistic output. His paintings, representative of the exuberant late Baroque style, are held by many great museums, including important collections in Naples, Valletta, and in his hometown of Taverna.

John Pettie
British Painter, 1839-1893 He was brought up in Edinburgh and East Lothian, and in 1855 he entered the schools of the Trustees' Academy, Edinburgh, sponsored by the history painter James Drummond (1816-77). He studied under Robert Scott Lauder, and among his fellow students were WILLIAM QUILLER ORCHARDSON, Thomas Graham (1840-1906), George Paul Chalmers (1833-78), John Burr (1831-93) and John MacWhirter, several of whom later became part of Pettie's circle of Scottish artist friends in London. Pettie first exhibited at the Royal Scottish Academy in 1858 with In Trabois House (untraced), a scene from Sir Walter Scott's The Fortunes of Nigel, and he began sending work to the Royal Academy in 1860. From 1858 he provided illustrations for the periodical Good Words, and, encouraged by the reviews received for his early Royal Academy exhibits, such as The Armourers (exh. RA 1860) and What D'Ye Lack' (exh. RA 1861), when Good Words transferred its headquarters, Pettie moved to London in 1862. He shared a studio in Fitzroy Square with Orchardson and Graham from 1863 until his marriage to Elizabeth Ann Bossom on 25 August 1865. He subsequently lived at various addresses, gravitating towards the wealthy artistic colony in St John's Wood, where in 1882, at 2 Fitzjohn's Avenue, he built a neo-Georgian house and studio, The Lothians (destr.). This reflected not only the professional circle in which Pettie moved but also the rapid financial success that he achieved in London. From the mid-1860s his most important patron was John Newton Mappin, founder of the Mappin Art Gallery,
