Italian High Renaissance Painter and Inventor, 1452-1519 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.   Related Paintings of LEONARDO da Vinci :. | Adoration of the Magi | The Anunciacion | Cecila Gallerani (mk45) | Profile of an old man | Study fur the Sforza monument |

pehr hillestrom
Pehr Hilleström (1732-1816) var en svensk målare och vävare, professor vid Konstakademiens läroverk från 1794 och dess direktör från 1810. I unga år var han en av Sveriges främsta gobelängvävare men övergick sedan till måleri. Han är mest känd för sina vardagsskildringar av sin tids levnadssätt. Han målade pigor och tjänstefolk som arbetar, överklassen i de fina salarna, enkelt folk i stugorna och bilder från olika bruksmiljöer. Genom det räknas han som den största skildraren av den gustavianska samtiden. Pehr Hilleström är far till konstnären Carl Petter Hilleström och farfars farfars far till Gustaf Hilleström. Pehr Hilleström föddes i 1732 Väddö, Roslagen, troligtvis den 18 november. Han växte upp under fattiga omständigheter på Väddö prästgård vid sin farbror som var kyrkoherde där. Han var son till en militär och äldst i en syskonskara på 12 barn. Hans far råkade redan 1719 i rysk fångenskap men hade 1723 lyckats återvända till Sverige och då tagit sin tillflykt till brodern på Väddö. 1743 flyttade familjen Hilleström från Roslagen till Stockholm, där Pehr, 10 år gammal, sattes i lära hos tapet- och landskapsmålaren Johan Philip Korn (1727-1796) samt mellan åren 1744-1747 även hos den invandrade tyske solfjädermålaren Christian Fehmer. Utöver detta fick han även undervisning vid kungliga ritareakademin där Guillaume Thomas Taraval (1701-1750) och Jean Eric Rehn (1717-1793) var läromästare. Efter inrådan från Carl Hårleman sattes Hilleström 1745 i lära hos Jean Louis Duru (-1753). Duru var hautelissevävare och hade kallats till Sverige för att göra textila utsmyckningen av Stockholms slott. Tanken var att Hilleström skulle utbildas till Durus medhjälpare. 1749 visade Hilleström upp ett första läroprov som visades upp för deputationen som gillade det så mycket så att han fick en belöning på 180 daler kopparmynt. När Duru dog i slutet av 1753 så fick Hilleström fullborda den påbörjade kappan för tronhimmelen i det kungliga audiensrummet. Han var då så skicklig att det knappt kunde märkas någon skillnad mellan hans och hans lärares arbete. Lönen var blygsam men vid 1756 års riksdag fick han samma årslön som Duru hade haft, och han fick en beställning på ett vävt porträtt av Hårleman utfört i hautelisse. Åren 1757-58 var Hilleström på en längre och för tidens konstnärer sedvanlig studieresa till utlandet. Färden gick till Paris, Belgien och Holland, bland annat med en vidareutbildning i gobelängteknikerna som mål. I Paris blir Hilleström erbjuden att studera måleri i François Bouchers atelj??, men störst intryck tog han där av genre- och stillebenmålaren Jean-Baptiste-Sim??on Chardin, som undervisade honom vid franska målarakademien. Väl hemma i Stockholm fortsatte han visserligen att göra tapeter, mattor, stolsöverdrag och dylikt för hovet. Men så småningom fylldes slottet behov av vävnader samtidigt som Hilleström fortsatte studera måleri.

Willem Van de Velde The Younger
(bapt. 18 December 1633 - 6 April 1707) was a Dutch marine painter. Willem van de Velde was baptised on 18 December 1633 in Leiden, Holland, Dutch Republic. A son of Willem van de Velde the Elder, also a painter of sea-pieces, Willem van de Velde, the younger, was instructed by his father, and afterwards by Simon de Vlieger, a marine painter of repute at the time, and had achieved great celebrity by his art before he came to London. In 1673 he moved to England, where he was engaged by Charles II, at a salary of £100, to aid his father in "taking and making draughts of sea-fights", his part of the work being to reproduce in color the drawings of the elder van de Velde. He was also patronized by the Duke of York and by various members of the nobility. He died on 6 April 1707 in London, England.
