From today's featured article

Musidora: The Bather 'At the Doubtful Breeze Alarmed', also known as The Bather, is a name given to four nearly identical oil paintings on canvas by English artist William Etty. The paintings illustrate a scene from James Thomson's 1727 poem Summer in which a young man accidentally sees a young woman bathing naked and is torn between his desire to look and his knowledge that he ought to look away. The scene was popular with English artists as it was one of the few legitimate pretexts to paint nudes at a time when the display and distribution of nude imagery was suppressed. Musidora was extremely well received when first exhibited and considered one of the finest works by an English artist. Etty died in 1849 and his work rapidly went out of fashion. At that time, the topic of Musidora itself became a cliche, and from the 1870s Thomson's writings faded into obscurity. Etty's Musidora is likely to have influenced The Knight Errant by John Everett Millais, but otherwise has had little effect. (Full article...)

Today's featured picture

The redtoothed triggerfish (Odonus niger) is a tropical fish in the family Balistidae, the triggerfishes. It is native to the tropical Indo-Pacific area, including the Red Sea, the African east coast, the Marquesas Islands and the Society Islands, across to southern Japan and the Great Barrier Reef of Australia. Redtoothed triggerfish are normally deep blue or purple with a light blue head. They are omnivorous and mostly opportunistic feeders, with crustaceans as its primary food source. They also feed on zooplankton and algae, and remains of cephalopods and fish have been found in their stomach. This redtoothed triggerfish was photographed off the coast of Anilao in the Philippines.
