Many scholars have created readily accessible online resources to aid both their colleagues and the general public to better understand the Greeks, the Romans, and many other cultures of Classical antiquity. Here is a list in alphabetical order of some of these websites.
Stanford University’s Orbis Project offers a geospatial model of the Roman Empire. Among other things, you can calculate how long it takes to travel from one point to another (on foot, using an ox cart or a horse, and so on), with different results depending on the season and so on.
Perhaps the most well known, and helpful, online resource for classicists and ancient historians is Perseus. It is a joint project, originally started at Tufts University, which transcribes ancient texts, in both the original language as well as (often) an English translation. Most of the authors and works cited on our website can be found on Perseus, allowing you to read for yourself the evidence upon which we have built our arguments. It also contains catalogues of texts from other eras, as well as a collection of archaeological materials which are searchable.
The Theoi Project by Aaron J. Atsma profiles each deity and creature of Greek mythology on a separate page, incorporating an encyclopedia summary, quotations from a wide selection of ancient Greek and Roman texts, and illustrations from ancient art.
A website that deals specifically with Aegean-style wall-paintings from Tell el-Dab’a in Egypt. It’s a joint venture of the Austrian Academy of Sciences in Vienna and the Ruhr-University Bochum; it is supported by the Austrian Archaeological Institute and currently funded by the Institute for Aegean Prehistory (INSTAP).
