Still more erotic features are present in «Yarilki», «send-off of Yarilo», another term based on the action, this time from «yariti» («to become excited», 4o get hot', 4o be filled with lust'). This festival also appears to have been moved from the same spot on the calendar and consists of customs from the same original complex. Ithyphallic Yarilo is another manifestation of Perun (it is connected with his sexual, marriage-making functions).
Thus, under the more modern forms described by the travelers, later ethnographers, and the students of folklore, one may discern the earlier content of the Kupalo's festival, Perun's send-off, which marked his downfall and death. This festival coincides by its original place on the calendar with the summer solstice. It is very likely that the old chronicler's description of Perun's overthrow (beating of idol by twelve men, deploring him by others, floating his statue down the river) was, in fact, misunderstood by the chronicler. It was actually a description of the regular ritual of Perun's send- off on the day of the summer solstice.
The next assumption must be that if there was a send-off, then there must be also the receiving of Perun, the annual Perun's reemergence, his resurrection or his birth. Indeed, on the opposite point of the calendar scale, at the time of the winter solstice, there is more than a week of completely pagan celebrations — Svyatki (modern New Year's feast). Among the Southern Slavs this holiday is marked by veneration of an oak log called Badnyak, to which the attributes of an anthropomorphic deity, an old man, are ascribed.
{Simultaneously, during the ceremony, a young Bozhise appears (a patronimic from «Bog», «god», so according to his name he is a son of god).
At that time (the winter solstice), the Russian peasants performed mummery. Among these performances, the «plays with umrun» are especially remarkable. «Umrun» is a dead man (from the Russian «umirať» — «to die»). The dead imitated by a mummer was supposedly brought back to life by sheer sexual actions. Among these were masturbation and fellation which wenches of the village were forced to perform. This method of reviving and rejuvenations, or method of resurrection, was connected with the belief in beneficial properties of male semen. The idea of reviving the dead was akin with ancient Indoeuropean idea of sansara (second life on the earth, movement of souls).
So, typologically, Perun appears to belong to the well known class of the dying and resurrecting gods. In accordance with the cycle of his festivals, the year in among the Eastern Slavs was divided into two halves (like among the Greeks, where the year was divided into apodemy and epidemy by the celebrations of Apollo's appearance and send-off). Yet, primarily due to the feasts of Apollo's meeting and send-off. Yet due to differences in climate and ecology, the points of the division were different among the different groups among the Slavs. The worship of Perun, like that of Apollo was conducted by women and girls.
