Easton's Bible Dictionary (1897)
Beautiful, the queen of Ahasuerus, who was deposed from her royal dignity because she refused to obey the king when he desired her to appear in the banqueting hall of Shushan the palace (Esther 1:10-12).
Smith's Bible Dictionary (1863)
(beautiful), the “queen” of Ahasuerus, who, for refusing to show herself to the king’s guests at the royal banquet, when sent for by the king, was repudiated and deposed. (Esther 1:1) ... ) Many attempts have been made to identify her with historical personages; but it is far more probable that she was only one of the inferior wives, dignified with the title of queen, whose name has utterly disappeared from history.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
