Joachim Anthoniszoon Wtewael (Dutch pronunciation: [ˈjoːaːxɪm ˈyːtəʋaːl]; 1566 – 1 August 1638), also known as Uytewael (pronounced [ˈœytəʋaːl]), was a Dutch Mannerist painter and draughtsman, as well as a highly successful flax merchant, and town councillor of Utrecht. Wtewael was one of the leading Dutch exponents of Northern Mannerism, and his distinctive and attractive style remained largely untouched by the naturalistic developments happening around him, "characterized by masterfully drawn, highly polished figures often set in capricious poses". Wtewael was trained in the style of late 16th-century Haarlem Mannerism and remained essentially faithful to it, despite painting well into the early period of Dutch Golden Age painting.
Altogether he has left about a hundred paintings, as well as drawings and some stained glass he designed. He painted a mixture of large paintings on canvas, and tiny cabinet paintings on copper plates, the latter the more numerous and typically the most distinctive. There is also a group of mid-sized paintings, often on panel. In all these sizes he painted a mixture of conventional religious subjects and mythological ones, the latter with a strong erotic element. Especially in his works on copper he returns to the same subjects in several works, but varying the compositions. The Adoration of the Shepherds, Venus and Mars Surprised by Vulcan, and the Feast of the Gods as the wedding feasts of Cupid and Psyche, Peleus and Thetis, the latter often combined with the Judgement of Paris, and Lot and His Daughters, are some examples of these favourite subjects. The first of these was painted in all sizes. Often the large paintings contain only a few figures, but the small and middle sized ones are extremely crowded compositions, the mythological ones typically including many nudes. In some works he also revived the kitchen scene subjects of Pieter Aertsen from a half century before. According to Seymour Slive, "When well preserved his little pictures glow like gems".
