Beautiful duotone lithograph, depicting Tophana (Tophane) Artillery Barracks in Constantinople (Istanbul).  Also known as the Taksim Artillery Barracks; unfortunately no longer extant. Right behind is the Nusretiye Mosque, constructed during the reign of Sultan Mahmud II.  Initialed in stone "J.F.L" lower right corner, and titled "Artillery Barracks, Tophana" in the lower left corner.  This print was published in 1838, after artwork done by John Frederick Lewis in 1837, that was based upon sketches made by Coke Smyth during his residence in Constantinople during the years 1835-36.  At the time, Lewis himself had not yet traveled to Constantinople.  Print size: 11 1/4 x 14 1/2 inches.  The small dots in each of the prints corners are alignment pinholes used in the lithograph's printing and are not defects.  Some foxing and toning to the the edges, but the print itself is in excellent condition.
 
John Frederick Lewis (1804–1876), was an English painter and printmaker who specialized in Mediterranean and Oriental scenes.  After being largely forgotten for decades, from the late 1970s on he became extremely fashionable, with his paintings commanding prices into the millions of dollars, and his prints now scarce.  John Richard Coke Smyth (1808-1882), was a British artist and traveler who produced several collections of prints from sketches made during his travels.
