 Having concluded that the Persian king in that book was Darius Hystaspes, Reggio shows that the main object of the writer was to prove that Darius was the first to establish the post.Analyzing the text carefully, Reggio maintains that Mordecai was by no means such a great man as the Rabbis declare him to have been, but that, on the contrary, he was an ordinary Jew; for he not only gave no religious education to his adopted daughter Esther, but he even commanded her to deny her race and religion.His refusal to bow before Haman was unnecessary, as such an act would not have violated any Jewish religious law.
