Battista di Biagio Sanguigni  (active 1393–1451),

 formerly known as the Master of 1419, was an Italian painter from the region around Florence in the first half of the 15th century. The painter's work bears a good deal of resemblance to that of Lorenzo Monaco. His previous name is derived from the central panel of a now-dismantled triptych, depicting the Madonna and Child Enthroned, commissioned by Antonio di Domenico Giugni for the church of Santa Maria in Latera and now held at the Cleveland Museum of Art; the picture is dated to 1419. Between 1425 and 1427 Battista painted another triptych, this one depicting Saint Julian and given to the college of San Gimignano; it shows the influence of Masolino da Panicale. The Hungarian art historian Miklós Boskovits was able to attribute an additional dozen or so works to him. A single side of a triptych was sold recently and achieved a price of over £400,000.
