The reputed author of an alphabetically arranged work in Greek, giving an account of persons and places and explanations of words, besides much miscellaneous information. The book is referred to as a "Lexicon", and bears evidence of having gone through many hands. It is accompanied by a prefatory statement that "the present book is by Suidas, but its arrangement is the work of twelve learned men". Nothing is known of Suidas, although he is usually placed in the tenth or eleventh century. The "Lexicon" is valued for its extracts from ancient writers whose works have in many cases perished.
