Such in sum are the salient features of the concluding utterances of that historic Proclamation, the opening notes of which were sounded during the latter part of Bahá’u’lláh’s banishment to Adrianople, and which closed during the early years of His incarceration in the prison-fortress of Akká. Kings and emperors, severally and collectively; the chief magistrates of the Republics of the American continent; ministers and ambassadors; the Sovereign Pontiff himself; the Vicar of the Prophet of Islám; the royal Trustee of the Kingdom of the Hidden Imám; the monarchs of Christendom, its patriarchs, archbishops, bishops, priests and monks; the recognized leaders of both the Sunní and _Sh_í’ah sacerdotal orders; the high priests of the Zoroastrian religion; the philosophers, the ecclesiastical leaders, the wise men and the inhabitants of Constantinople—that proud seat of both the Sultanate and the Caliphate; the entire company of the professed adherents of the Zoroastrian, the Jewish, the Christian and Muslim Faiths; the people of the Bayán; the wise men of the world, its men of letters, its poets, its mystics, its tradesmen, the elected representatives of its peoples; His own countrymen—all have, at one time or another, in books, Epistles, and Tablets, been brought directly within the purview of the exhortations, the warnings, the appeals, the declarations and the prophecies which constitute the theme of His momentous summons to the leaders of mankind—a summons which stands unparalleled in the annals of any previous religion, and to which the messages directed by the Prophet of Islám to some of the rulers among His contemporaries alone offer a faint resemblance.
