The Prado, Spain's premier art museum, has a browsable and searchable website interface of its rich collection. Readers may wish to begin by reading the short essay by museum director Miguel Falomir. This essay explains that since the Prado's collection was initially amassed by Spain's sixteenth- and seventeenth-century monarchs it is therefore based on their tastes in art, which has resulted in gaps in the collection and some time periods that are less well represented than others. That caveat aside, the website is extremely easy to use, beginning with a digital gallery of Masterpieces such as Fra Angelico's fifteenth-century altarpiece The Annunciation, and includes other famous artists such as Rembrandt, Goya, Durer, and Raphael. There is also an alphabetical listing of artists and a set of themes (e.g. saints, royal portrait, or social realism/everyday life) that can be browsed. If the browsing features do not reveal a work of interest, readers can also use a comprehensive search feature that can retrieve results based on artist, title, technique, and support, and more.
