a Greek writer, according to some, flourished in the 11th century, under the reign of the emperor Alexius Comnenus; according to others, before the 10th century. He wrote in Greek an Historical and Geographical Dictionary or Lexicon; a work which, though not always strictly accurate, is nevertheless of great importance, as it contains many things taken from the ancients that are nowhere else to be found. The best edition of Suidas is that of Kufler, in Greek and Latin, with notes, printed in 3 vols. fol. which has been much improved by Toup.
