Editing Guercino (section)

==Style==
Guercino was remarkable for the extreme rapidity of his executions: he completed no fewer than 106 large altarpieces for churches, and his other paintings amount to about 144. He was also a prolific draftsman. His production includes many drawings, usually in ink, washed ink, or red chalk. Most of them were made as preparatory studies for his paintings, but he also drew landscapes, [[Genre works|genre subjects]], and caricatures for his own enjoyment. Guercino's drawings are known for their fluent style in which "rapid, calligraphic pen strokes combined with dots, dashes, and parallel hatching lines describe the forms".<ref>Griswold 1991, p. 36</ref>

Despite presumably having [[monocular vision]] due to a [[Amblyopia#Strabismus|'lazy']] right eye, Guercino showed remarkable facility to [[Depth perception|imply depth]] in his works, perhaps assisted by an enhanced [[Contrast (vision)|perception of light and shade]] thanks to compensation by the healthy eye.<ref name="Scholtz2019">Scholtz et al, 2019</ref> Other artists with different types of strabismus include [[Rembrandt]], [[Dürer]], [[Degas]], [[Picasso]] and (possibly) [[Leonardo da Vinci]].<ref>{{cite journal |last1=Tyler |first1=CW |title=Evidence That Leonardo da Vinci Had Strabismus. |journal=JAMA Ophthalmology |volume=137 |issue=1 |pages=82–86 |date=18 October 2018 |doi=10.1001/jamaophthalmol.2018.3833 |pmid=30347053 |url=https://christophertyler.org/CWTyler/Art%20Investigations/ART%20PDFs/Tyler_JAMA-0_180017.pdf |pmc=6439801}}</ref>

His lively treatment of the [[Aurora (mythology)|Aurora myth]] (1621, [[Casino di Villa Boncompagni Ludovisi|Villa Aurora]], Rome, Italy), painted for the pope's nephew, Cardinal [[Ludovico Ludovisi]].<ref>Vodret and Gozzi, 2011, pp. 159–161</ref> challenges the more measured representation of the same subject [[Aurora (Guido Reni)|painted by Guido Reni]] at [[Palazzo Pallavicini-Rospigliosi|Palazzo Rospigliosi]] on behalf of a Ludovisi family rival [[Scipione Borghese]] and makes a statement of political triumph.<ref>Unger, 2016, p. 9; {{cite web |title=Aurora by Guercino |url=https://www.wga.hu/html_m/g/guercino/3/05aurora.html |website=www.wga.hu |publisher=Web Gallery of Art |access-date=15 February 2019}}</ref> Some of his later works are closer to the style of Reni, and are painted with much greater luminosity and clarity than his early works with their prominent use of chiaroscuro.
