Although the historical accounts differ somewhat, the Deposition that is celebrated today took place most likely during the reign of Emperor Arcadius (395-408), when the precious Cincture of the Mother of God was brought from Zela of Cappadocia to Constantinople, and placed in the Church of the Theotokos in the section of Chalcopratia.

For the maintenance of their armed forces, the Roman emperors decreed that their subjects in every district should be taxed every year. This same decree was reissued every fifteen years, since the Roman soldiers were obliged to serve for fifteen years. At the end of each fifteen-year period, an assessment was made of what economic changes had taken place, and a new tax was decreed, which was to be paid over the span of the fifteen years. This imperial decree, which was issued before the season of winter, was named Indictio, that is, Definiton, or Order. This name was adopted by the emperors in Constantinople also. At other times, the latter also used the term Epinemisis, that is, Distribution (Dianome). It is commonly held that Saint Constantine the Great introduced the Indiction decrees in A.D. 312, after he beheld the sign of the Cross in heaven and vanquished Maxentius and was proclaimed Emperor in the West. Some, however (and this seems more likely), ascribe the institution of the Indiction to Augustus Caesar, three years before the birth of Christ. Those who hold this view offer as proof the papal bull issued in A.D. 781 which is dated thus: Anno IV, Indictionis LIII -that is, the fourth year of the fifty-third Indiction. From this, we can deduce the aforementioned year (3 B.C.) by multiplying the fifty-two complete Indictions by the number of years in each (15), and adding the three years of the fifty-third Indiction. There are three types of Indictions: 1) That which was introduced in the West, and which is called Imperial, or Caesarean, or Constantinian, and which begins on the 24th of September; 2) The so-called Papal Indiction, which begins on the 1st of January; and 3) The Constantinopolitan, which was adopted by the Patriarchs of that city after the fall of the Eastern Empire in 1453. This Indiction is indicated in their own hand on the decrees they issue, without the numeration of the fifteen years. This Indiction begins on the 1st of September and is observed with special ceremony in the Church. Since the completion of each year takes place, as it were, with the harvest and gathering of the crops into storehouses, and we begin anew from henceforth the sowing of seed in the earth for the production of future crops, September is considered the beginning of the New Year. The Church also keeps festival this day, beseeching God for fair weather, seasonable rains, and an abundance of the fruits of the earth. The Holy Scriptures (Lev. 23:24-5 and Num. 29:1-2) also testify that the people of Israel celebrated the feast of the Blowing of the Trumpets on this day, offering hymns of thanksgiving. In addition to all the aforesaid, on this feast we also commemorate our Saviour's entry into the synagogue in Nazareth, where He was given the book of the Prophet Esaias to read, and He opened it and found the place where it is written, "The Spirit of the Lord is upon Me, for which cause He hath anointed Me..." (Luke 4:16-30).

It should be noted that to the present day, the Church has always celebrated the beginning of the New Year on September 1. This was the custom in Constantinople until its fall in 1453 and in Russia until the reign of Peter I. September 1 is still festively celebrated as the New Year at the Patriarchate of Constantinople; among the Jews also the New Year, although reckoned according to a moveable calendar, usually falls in September. The service of the Menaion for January 1 is for our Lord's Circumcision and for the memorial of Saint Basil the Great, without any mention of its being the beginning of a new year.

The Prophet Moses-whose name means "one who draws forth," or "is drawn from," that is, from the water-was the pinnacle of the lovers of wisdom, the supremely wise lawgiver, the most ancient historian of all. He was of the tribe of Levi, the son of Amram and Jochabed (Num. 26:59). He was born in Egypt in the seventeenth century before Christ. While yet a babe of three months, he was placed in a basket made of papyrus and covered with pitch, and cast into the streams of the Nile for fear of Pharaoh's decree to the mid-wives of the Hebrews, that all the male children of the Hebrews be put to death. He was taken up from the river by Pharaoh's daughter, became her adopted son, and was reared and dwelt in the King's palace for forty years. Afterward, when he was some sixty years old, he fled to Madian, where, on Mount Horeb, he saw the vision of the burning bush. Thus he was ordained by God to lead Israel and bring it out of the land of Egypt. He led Israel through the Red Sea as it were dry land and governed the people for forty years. He wrought many signs and wonders, and wrote the first five books of the Old Testament, which are called the Pentateuch. When he reached the land of Moab, he ascended Mount Nabau, on the peak called Phasga, and there, by divine command, he reposed in the sixteenth century before Christ, having lived for some 120 years. The first two Odes of the Old Testament, "Let us sing to the Lord" and "Attend, O heaven, and I will speak," were written by him. Of these hymns, the first was chanted by the shore of the Red Sea as soon as the Israelites had crossed it; the second, in the land of Moab, a few days before his repose. The Holy High Priest Aaron was the elder brother of the Holy Prophet Moses. He was appointed by God to serve as the spokesman of Moses before the people, and also before Pharaoh, in Egypt. Afterwards, in the wilderness, he was called to the ministry of the high priesthood, as narrated in the books of Exodus, Leviticus, and Numbers in the Old Testament. The name Aaron means "enlightened."

According to the opinion of many Fathers of the Church, based on an ancient tradition, this is the Zacharias whom, as our Lord said, the Jews slew between the temple and the altar (Matt. 23:35), first, because even after the Virgin Mary gave birth, he continued to refer to her as virgin and number her among the virgins; second, because Zacharias' son John was not found during the slaughter of the Innocents, since the elderly Elizabeth had taken him and carefully hid him while he was yet an infant, in an unnamed place somewhere in the desert, where, according to the Evangelist, "the child grew, and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel" (Luke 1:80). When the child was not found, his father was slain by Herod's command.
