Darius the Great at Persepolis

Is this stone carving a portrait of Darius the King mentioned in the Book of Ezra? Darius the Great is seated on his throne in his reception chamber while an audience of delegates from provinces around his mighty empire approach him to bring him tribute. This particular dignitary is raising one hand to his mouth as a token of respect and honor and with the other hand he holds his staff of office showing that he was a commander and prime minister of the Medes, as seen by his round cap and uniform. Behind him are two Persian attendants holding a spear and a container of incense. Notice Darius the Great is holding his sceptre of authority in his right hand and a budding flower in his left. Behind Darius is standing the crown-prince Xerxes. This relief of king Darius I Seated is an important discovery in Biblical Archaeology and confirms what the Bible says regarding Darius and the Persian Empire. "They sent a letter unto him, wherein was written thus; Unto Darius the king, all peace." Ezra 5:7 Esther 4:11 "All the king's servants, and the people of the king's provinces, do know, that whosoever, whether man or women, shall come unto the king into the inner court, who is not called, there is one law of his to put him to death, except such to whom the king shall hold out the golden sceptre, that he may live: but I have not been called to come in unto the king these thirty days." Esther 5:2 "And it was so, when the king saw Esther the queen standing in the court, that she obtained favour in his sight: and the king held out to Esther the golden sceptre that was in his hand. So Esther drew near, and touched the top of the sceptre."
