"The Suda (or Stronghold) is a massive 10thcentury Byzantine Greek historical encyclopedia of the ancient Mediterranean world, covering the whole of Greek and Roman antiquity and also including Biblical and Christian material.
"Preserved in several medieval manuscripts, it has been edited and published several times since the end of the 14th century in traditional hard-copy scholarly editions, most recently that of Ada Adler (Teubner, 5 volumes: 1928-1938, reprinted 1971). The Suda On Line (SOL) project, begun in 1998 as part of the Stoa Consortium, opens up this stronghold of information by means of a freely accessible, keyword-searchable database, with English translations, notes, bibliography, and links to other electronic resources. With contributions (as Translators and/or Editors) from more than two hundred people worldwide, the SOL reached the landmark of all entries being translated and “vetted” (edited) to a usable standard on July 21, 2014. But more can, and will, be done."
The online Suda is a tremendous resource for scholars working on all aspects of antiquity. You can't get too far in researching theurgy or some of the more obscure figures in the Neo-Platonic tradition without having to visit the Suda. How wonderful to have it online!
