Grotefend made further guesses about the remaining words in the inscriptions, and endeavoured to rebuild probable sentences. Again relying on deductions only, and without knowing the actual script or language, Grotefend guessed a complete translation of the Xerxes inscription (Niebuhr inscription 2): "Xerxes the strong King, King of Kings, son of Darius the King, ruler of the world" (""Xerxes Rex fortis, Rex regum, Darii Regis Filius, orbis rector""). In effect, he achievied a fairly close translation, as the modern translation is: "Xerxes the Great King, King of Kings, son of Darius the King, an Achaemenian".
