BAILLI, or BAILLY, David, a painter of perspective views and portraits, was the son of Peter Bailly, an artist of some note, and was born at Leyden in 1588. From his father he learned to draw and design. He afterwards studied under Adrian Verburg, and then under Cornelius Vandervoort, with whom he spent about six years. Vandervoort possessed many capital paintings of some great masters, which Balli, for his own improvement, copied with great care. One perspective view of the interior of a church, by Stenwyck, he finished with such accuracy, that Stenwyck himself could scarcely determine which of the two was the original. After this he travelled in Italy, and spent some years at Rome. In the latter part of his life, he devoted himself to portraits drawn with the pen, which are characterized by great force and roundness. He died in 1638.
