These couriers were called in the Persian language by a name signifying, as near as we can comprehend it, “service by compulsion.” The superintendency of the posts became a considerable employment. Darius, the last of the Persian kings, had it before he came to the crown. Xenophon notices the fact that this establishment subsisted still in his time, which perfectly agrees with what is related in the book of Esther concerning the edict published by Ahasuerus in favor of the Jews, which edict was carried through that vast empire with a rapidity that would have been impossible without these posts erected by Cyrus.[3] Persia, in some respects, has not kept pace with the progress of other nations, or carried out those plans of government and schemes which Cyrus originated in his early reign. Traces of a race far more energetic than the present inhabitants of Persia are found in various parts of the kingdom. The ruins of many ancient cities scattered over the land are imposing and grand, especially those of Persepolis. Next to the pyramids of Egypt and the colossal ruins of Thebes, they have attracted the attention of travellers, and, like them, still remain an enigma,—their history, dates, and objects being involved in the gloom of antiquity. These evidences prove the existence of a state of refinement in art in the sixth century, scarcely equalled, certainly not excelled, since, and fully sustain the _data_ given to that wonderful discovery,—the establishing the postal system and the first introduction of the “riding-post.”[4] In the highest eras of their civilization, neither the Greeks nor the Romans had a public letter-post; though the conveyance of letters is as much a matter of necessity and convenience as the conveyance of persons and merchandise. There were _stationese_ and mounted messengers, called _tabellarii_, who went in charge of the public despatches; but they were strictly forbidden to convey letters for private persons. In the time of Augustus, post-houses were established throughout the kingdom, and post-horses stationed at equal distances to facilitate the transmission of letters, &c. Under his reign, literature flourished, many salutary laws were established, and he so embellished Rome that he was declared “to have found it brick and left it marble.” He was born at Rome, B.C. 63, died at Nola in the seventy-sixth year of his age. We have alluded to the fact of nations, considerably advanced in civilization at the early period of the world’s history, being without a public post for the conveyance of letters. Yet, when we take into consideration that trade and commerce were then in their infancy, simple messengers only were required. Indeed, letters at that period were only written when great occasions called them forth. What with us is now a pleasure, was with the ancients a task.
