The Ancients expressed their religious beliefs in a dramatic way on a number of occasions throughout the year. The festivities were held in the Spring, Autumn, or Winter. These were to commemorate the activities of the sun, his renewed activity in the Spring calling forth rejoicing and his decline in the Fall being the cause of sorrow and lamentation. As well as the festivities, there were the various mysteries, such as the Eleusinia, the Dionysia and the Bacchanalia. These were conducted by the priests who moulded religious beliefs and guarded their secrets. The mysteries were of the utmost importance and the most sacred of religious conceptions were here dramatized. Mythology also gave expression to the religious ideas of the time and we find that the most important myths, dramatically produced at the religious festivals, were sun myths. The annual festivities and mysteries will be discussed together because both were intended to dramatize the same beliefs. Both were under priestly control and so were national institutions. The festivals were for the common people but the mysteries were fully understood only to the initiated. While no very clear account of the mysteries has been given, a certain theme seems to run through them all, and this is found in the myths as well. A drama is enacted, in which the god is lost, is lamented, and is found or returns amid great rejoicing.[15] This was enacted in Egypt where the mourning was for Osiris; and in Greece for Adonis, and later for Bacchus. All these are, of course, sun gods, and the whole dramatization or myth is in keeping with the activities of the sun. On these occasions, the main object seems to have been to restore the lost god, or to insure his reappearance. The women took the leading part and mourned for Osiris, Adonis or Bacchus. They wandered about the country at night in the most frenzied fashion, avoided all men and sought the god. At times, during the winter festival, the quest would be fruitless. In the Spring, when they indulged themselves in all sorts of orgies and extravagances, Adonis was found.
