Introduction The dispute between rationalism and empiricism takes place within epistemology, the branch of philosophy devoted to studying the nature, sources and limits of knowledge.
While the use of optical aids would generally enhance accuracy, Falco calculated the types of distortion that would result from specific optical devices; Hockney and Falco argued that such errors could in fact be found in A thesis statement can be controversial work of some of the Old Masters.
In particular, it has spurred increased interest in the actual methods and techniques of artists among scientists and historians of scienceas well as general historians and art historians. The latter have in general reacted unfavorably, interpreting the Hockney—Falco thesis as an accusation that the Old Masters "cheated" and intentionally obscured their methods.
Stork and several co-authors have argued against the Hockney—Falco thesis from a technical standpoint. He was struck by the accuracy of portraits by Jean Auguste Dominique Ingresand became convinced that Ingres had used a camera lucida or similar device.
From there, Hockney began looking for signs of the use of optical aids in earlier paintings, creating what he called the Great Wall in his studio by organizing images of great realistic art by time period.
InHockney published an extended form of his argument in Secret Knowledge.
The hypothesis that technology was used in the production of Renaissance Art was not much in dispute in early studies and literature. Hockney suggests that later artists, beginning with Caravaggioused convex mirrors as well, to achieve a large field of view.
The 15th century work of Jan van Eyck seems to be the turning point, he argues, after which elements of realism became increasingly prominent. He correlates shifts toward increased realism with advances in optical technologies. The argument of Secret Knowledge is primarily a visual one, as Hockney was largely unable to determine when and how optical aids were used by textual or direct evidence.

How to Generate a Thesis Statement if the Topic is Assigned. Almost all assignments, no matter how complicated, can be reduced to a single question.
Stork analyzed the images used by Falco and Hockney, and came to the conclusion that they do not demonstrate the kinds of optical distortion that curved mirrors or converging lenses would cause. Historians are more inclined to agree about the possible relevance of the thesis between and the invention of the telescope, and cautiously supportive after that period, when there clearly was interest and capacity to project realistic images; 17th century painters such as Johannes Vermeer and Gaspar van Wittel used optical devices in a variety of ways, though not the ways postulated by Hockney.
Leonardo also describes a camera obscura in his Codex Atlanticus of — The camera obscura was well known for centuries and documented by Ibn al-Haitham in his Book of Optics of — In 13th-century England Roger Bacon described the use of a camera obscura for the safe observation of solar eclipsesexactly because the viewer looks at the projected image and not the sun itself.
These manuscripts not only describe methods for making mirrors and parabolic mirrors but also discuss their use for image projection.
Optical glass[ edit ] Sara J. Schechner claimed that surviving glassware from the 15th and 16th centuries is far too imperfect to have been used to create realistic images, while "even thinking about projecting images was alien to the contemporary conceptual frame of mind. Dutch draper and pioneering microbiologist Antonie van Leeuwenhoek —a contemporary of artist Vermeer and an executor for Vermeer when he died in in Delft was known to have exceptional lens making skills, having created single small lenses capable of x magnification, far exceeding those of more complex compound microscopes of the period.
Indeed, his feats of lens making were not matched for a considerable time as he kept aspects of their construction secret; in the s, C. Stong used thin glass thread fusing instead of polishing to recreate Leeuwenhoek design microscopes.
It was long believed that Antonie van Leeuwenhoek was a master lens grinder a notion repeated in the recent BBC television documentary "Cell".
However, it is now believed[ by whom? Van Eyck also left his signature above this mirror,  showing the importance of the tool. The painting includes a crown glass window in the upper left side, a rather expensive luxury at the time.
Van Eyck was rather fascinated by glass and its qualities, which was as well of high symbolic importance for his contemporaries. Vermeer might have created his paintings aided by an optical device, as Jenison demonstrates by recreating a Vermeer painting.The Purdue University Online Writing Lab serves writers from around the world and the Purdue University Writing Lab helps writers on Purdue's campus.

The Hockney–Falco thesis is a theory of art history, advanced by artist David Hockney and physicist Charles M. urbanagricultureinitiative.com claimed that advances in realism and accuracy in the history of Western art since the Renaissance were primarily the result of optical instruments such as the camera obscura, camera lucida, and curved mirrors, rather than solely due to the development of artistic.
