A good place to muse on oil painting in Western art history online, I find, is at this site at wahooart.com. There is a hugearchive of digital images of artwork now housed in art museums around the world.The company makes canvas prints and hand-painted, oil painting reproductions to order, from your selection of imagesfrom this big archives.It's some resource for art lovers and historians. There are many images of works by famous artists of the past that I havenever seen.From their home page at wahooart.com, you can browse by the hundreds of artists there, movements in art, art media,historical timeline and even by subject matter. There is much biographical information about the artists.I am always fascinated by the way the 19th century English landscape painter, William Turner, used layers of luminousoil paint to recreate his blazing landscapes. Clicking http://EN.WahooArt.com/@/WilliamTurner , I find his paintings indexed in a floating 3D gallery at the site.
