I found this page yesterday. It’s a very nice resource for information and inspiration. They have information of every artist in Europe from the 12th to mid-19th centuries. They also have images and information of the artists’ works. It even plays classical background music which adds to the viewing experience (Though it only plays in the Home page). And if you need to find a specific artist but you don’t know their names, it has a search engine that let’s you specify the artist’s school, period, and profession to make searching easier.
The Web Gallery of Art is a virtual museum and searchable database of European painting and sculpture from 12th to mid-19th centuries. It was started in 1996 as a topical site of the Renaissance art, originated in the Italian city-states of the 14th century and spread to other countries in the 15th and 16th centuries. Intending to present Renaissance art as comprehensively as possible, the scope of the collection was later extended to show its Medieval roots as well as its evolution to Baroque and Rococo via Mannerism. More recently the periods of Neoclassicism and Romanticism were also included.
Have a nice day
