Image database on Pompey the Great and his accomplishments, including the construction of Rome’s first permanent theater building. Images include not just ruins but plans and drawings from throughout history.
A community of scholars, both teachers and students, who create online resources for teaching about the Latin language and ancient Roman culture. The project includes a collection of freely accessible resources, including a large searchable archive of digital images relating to classical antiquity. (Try searches for "comedy," "slaves," actors," etc.)
This work is most important for our commentary reports – William Smith's Dictionary of Roman Antiquities.
Smith is an encyclopedic work containing a lot of good basic information (and references to primary sources), published in 1875; it is thus an educational resource in the public domain. It is illustrated with its own woodcuts and some additional photographs added by Bill Thayer, creator of Lacus Curtius. You can find information and primary citations about things like theaters and other entertainment structures, dance, holidays, social customs, marriage & children, slaves, law, religion, clothing, and an awful lot more.
