Leonardo Da Vinci
Italian High Renaissance Painter and Inventor, 1452-1519
Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke.
The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful.
Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology.
Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists.
Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.

Garofalo's career began attached to the court of the Duke d'Este. His early works have been described as "idyllic", but they often conform to the elaborate conceits favored by the artistically refined Ferrarese court.
Born in Ferrara, Tisi is claimed to have apprenticed under Panetti and perhaps Costa and was a contemporary, and sometimes collaborator with Dosso Dossi. In 1495 he worked at Cremona under Boccaccino, who initiated him into Venetian colouring. He may have spent three years (1509 - 1512), in Rome. This led to a stylized classical style, more influenced by Giulio Romano.
Invited by a Ferrarese gentleman, Geronimo Sagrato, to Rome, he worked briefly under Raphael in the decoration of the Stanza della Segnatura. From Rome family affairs recalled him to Ferrara; there Duke Alfonso I commissioned him to execute paintings, along with the Dossi, in the Delizia di Belriguardo and in other palaces. Thus the style of Tisi partakes of the Lombard, the Roman and the Venetian modes.
He painted extensively in Ferrara, both in oil and in fresco, two of his principal works being the "Massacre of the Innocents" (1519), in the church of S. Francesco, and his masterpiece "Betrayal of Christ" (1524). For the former he made clay models for study and a clay figure. He continued constantly at work until in 1550 blindness overtook him, painting on all feast-days in monasteries for the love of God. He had married at the age forty-eight, and died at Ferrara on the 6th (or 16th) of September 1559, leaving two children.
Garofalo combined sacred inventions with some very familiar details. A certain archaism of style, with a strong glow of colour, suffices to distinguish from the true method of Raphael even those pictures in which he most closely resembles the great masterthis sometimes very closely; but the work of Garofalo is seldom free from a certain trim pettiness of feeling and manner.
Stanley, Owen1811 - 1850,was commander of HMS Rattlesnake on a four year exploratory expedition to New Guinea, 1846?C1850. Stanley was the son of Edward Stanley, Bishop of Norwich. He left naval college at the age of fifteen, and served under Phillip Parker King on HMS Adventure and John Franklin in the Mediterranean. In 1836 he sailed to the Arctic as scientific officer on HMS Terror under George Back. In 1838 he was given command of HMS Britomart and sailed to Australia, returning in 1843. In December 1846 Stanley sailed from Portsmouth in charge of HMS Rattlesnake, with the purpose of surveying the seas around the Great Barrier Reef and Torres Strait. The ship called at Madeira, Rio de Janeiro, Simon's Town and Mauritius, arriving in Sydney in July 1847. T.Dart WalkerIllustrator and marine artist
