This index is a comprehensive guide to the books, journal articles, and other publications that have been published since 1924 on all aspects of Greco-Roman antiquity and the early Christian world, from 2000 BCE to 800 CE. Some of its annotations are in French, but don't let that scare you. It is searched in English, and it will alert you to the existence of many publications written in English.
This is the basic index to journal articles published since 1929 in the field of art. Once you are ready to start looking for articles on your subject, you should always look here first. The full text (but often not the illustrations) of some of these articles is available online back to 1995.
This database contains more than 2.5 million high-quality digital images that are freely available for educational and research use. Containing reproductions of a wide range of works of art and architecture from all times and places throughout the world, it is an excellent source in which to find images of buildings and works of art from ancient Greece and Rome.
Originally founded by James Loeb in 1911 to make available all the written works surviving from the ancient Greek and Roman world, this database provides fully searchable, high-quality online editions of the original texts in Greek and Latin, with English translations facing them. This is an excellent place for finding the primary sources in which ancient authors told us about their world.
This is perhaps the most important single free Web site in the field of classical studies. It supplies the text in Greek, Latin, and (often) English translation of the works of many ancient authors. It also provides the texts of more recent books on aspects of the ancient world, and thousands of pictures of art objects, sites, and buildings. If you do research on the ancient world on the free Internet, and don't check out the Perseus Digital Library, your research will simply be incomplete.
