The Web Gallery of Art was opened in October 1996 with 1.100 images representing Italian Renaissance painting and sculpture. The images were presented in a simple html structure providing limited search possibilities. From this time on, the number of images continuously increased, and significant developments took place in the timeframe and content of the collection which now covers comprehensively the European (Western) painting, sculpture and graphic arts from 200 to 1900. Less complete but substantially covered are the sections of Medieval and Renaissance illuminations, decorative arts, and architecture. In the table below, the most important milestones in the development process are summarized. |
