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.
DAMOS is an annotated electronic corpus of all the published Mycenaean texts, the earliest – ca. fifteenth to seventeenth centuries BC – written evidence of the Greek language. It consists entirely of inscriptions in the Linear B syllabic script. You can search for specific tablets or words.
This website by the University of Oxford offers a selection of nearly 400 literary compositions from ancient Mesopotamia (modern Iraq), which date to the late third and early second millennia BC. It offers transliterations, as well as English prose translations.
Bill Thayer’s website features more than fifty Greek and Latin texts with English translation, including works by Cicero, Manetho, Plutarch, Suetonius, and Strabo. Also includes inscriptions and a number of books on the Classical world that are currently in the public domain.
The Lexicon of Greek Personal Names aims to collect all ancient Greek names used for individuals across all periods of Greek history. There are seven volumes in total (numbered I through V, with III and V divided into A and B) featuring thousands of names. Fortunately, there’s an option to search for specific names, and the volume in which the names are given should provide you with an idea of the regions in which the name was current. Also contains useful background information on Greek personal names.
