In 1642 a German soldier Ludwig von Siegen (ca. 1609–ca. 1680) developed a spiked roulette wheel, which could be run over the metal plate to make the process of stippling easier and quicker. The method became prevalent during the following century. Stipple images were usually printed in colour, with red being the most common.\r\nThe stippling wheel could be used either directly on the plate to create a series of small pits in the metal or with the etching print process by being run through etching ground exposing the metal, which was then etched. When printed, the resultant image was composed of dots. It could be touched up with line work where needed. It is possible to tell an engraved stipple image from the etched versions by looking at the shape of the dots through a magnifier; more regular triangular shapes were created in the engraved method, while the etched dots were less well defined, since they were bitten by acid. This plate was engraved.","physicalDescription":"Portrait of Leonardo da Vinci","artistMakerPerson":[{"name":{"text":"Bartolozzi, Francesco RA","id":"A1516"},"association":{"text":"artist","id":"AAT25103"},"note":""},{"name":{"text":"da Vinci, Leonardo","id":"A12588"},"association":{"text":"artist","id":"AAT25103"},"note":"after"}],"artistMakerOrganisations":[],"artistMakerPeople":[],"materials":[{"text":"copper","id":"AAT11020"}],"techniques":[{"text":"stipple","id":"AAT53239"}],"materialsAndTechniques":"Copper and stipple","categories":[{"text":"Prints","id":"THES48903"},{"text":"Portraits","id":"THES48906"},{"text":"Printmaking techniques","id":"THES252987"}],"styles":[],"collectionCode":{"text":"PDP","id":"THES48595"},"images":["2025PJ2096"],"imageResolution":"high","galleryLocations":[{"current":{"text":"LVLF","id":"THES49656"},"free":"","case":"EDUC","shelf":"9","box":"G"}],"partTypes":[[{"text":"printing plates","id":"AAT22755"}],[{"text":"copper plates","id":"THES403268"}]],"contentWarnings":[{"apprise":"","note":""}],"placesOfOrigin":[{"place":{"text":"Europe","id":"x28842"},"association":{"text":"printed","id":"AAT53319"},"note":""}],"productionDates":[{"date":{"text":"late 19th century-1917","earliest":"1850-01-01","latest":"1917-12-31"},"association":{"text":"printed","id":"AAT53319"},"note":""}],"associatedObjects":[{"object":{"text":"E.2128A-1917","id":"O117956"},"association":"Version"}],"creditLine":"","dimensions":[{"dimension":"Height","value":"32.7","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""},{"dimension":"Width","value":"24.5","unit":"cm","qualifier":"","date":{"text":"","earliest":null,"latest":null},"part":"","note":""},{"dimension":"Depth","value":"1","unit":"mm","qualifier":"approx","date":{"text":"","earliest":null,"latest":null},"part":"plate thickness","note":""}],"dimensionsNote":"","marksAndInscriptions":[{"content":"LEONARDO-  / VINCI","inscriber":{"name":{"text":"","id":""},"association":{"text":"","id":""}},"date":{"text":"","earliest":null,"latest":null},"description":"","interpretation":"","language":"","medium":"","method":"","position":"","script":"","translation":"","transliteration":"","type":"","note":"Lower centre (reversed)"},{"content":"From the Original Drawing by Leonardo da Vinci.","inscriber":{"name":{"text":"","id":""},"association":{"text":"","id":""}},"date":{"text":"","earliest":null,"latest":null},"description":"","interpretation":"","language":"","medium":"","method":"","position":"","script":"","translation":"","transliteration":"","type":"","note":"Lower right (reversed)"},{"content":"Engraved by F.
