Now that ancientlibrary.com, with its absolutely marvelous version of William Smith's Dictionary of Greek and Roman Biography and Mythology is not working now for a few weeks ( - it was an awesome site with a great interface), this is the next best one. I use this thing constantly, and am very sad ancientlibrary.com is gone now it seems, but I'll have to use this now.

A Dictionary of Greek and Roman Antiquities

A Dictionary of Greek and Roman Biography and Mythology - Vol I (names A - D)
http://www.hti.umich.edu/cgi/t/text/...L3129.0001.001

A Dictionary of Greek and Roman Biography and Mythology - Vol II (names E - N)
http://www.hti.umich.edu/cgi/t/text/...L3129.0002.001

A Dictionary of Greek and Roman Biography and Mythology - Vol III (names O - Z)
http://www.hti.umich.edu/cgi/t/text/...L3129.0003.001

It considers them three separate books, so you have to realize the entries (always with LATIN spelling of names, so Spartacus not Spartakos, etc.) will only be found by search within the right book.
