In Burmah the great festival of the year is the full moon of October, following the Buddhist Lent season (which is also the wet season), during which there is no sexual intercourse. The other great festival is the New Year in March.[134] In classical times the great festivals were held at the same time as in northern and modern Europe. The _brumalia_ took place in midwinter, when the days were shortest, and the _rosalia_, according to early custom in May or June, and at a later time about Easter. After the establishment of Christianity the Church made constant efforts to suppress this latter festival, and it was referred to by an eighth century council as "a wicked and reprehensible holiday-making." These festivals appear to be intimately associated with Dionysus worship, and the flower-festival of Dionysus, as well as the Roman Liberales in honor of Bacchus, was celebrated in March with worship of Priapus. The festivals of the Delian Apollo and of Artemis, both took place during the first week in May and the Roman Bacchanales in October.[135] The mediæval Feast of Fools was to a large extent a seasonal orgy licensed by the Church. It may be traced directly back through the barbatories of the lower empire to the Roman _saturnalia_, and at Sens, the ancient ecclesiastical metropolis of France, it was held at about the same time as the _saturnalia_, on the Feast of the Circumcision, i.e., New Year's Day. It was not, however, always held at this time; thus at Evreux it took place on the 1st of May.[136] The Easter bonfires of northern-central Europe, the Midsummer (St. John's Eve) fires of southern-central Europe, still bear witness to the ancient festivals.[137] There is certainly a connection between these bonfires and erotic festivals; it is noteworthy that they occur chiefly at the period of spring and early summer, which, on other grounds, is widely regarded as the time for the increase of the sexual instinct, while the less frequent period for the bonfires is that of the minor sexual climax. Mannhardt was perhaps the first to show how intimately these spring and early summer festivals--held with bonfires and dances and the music of violin--have been associated with love-making and the choice of a mate.[138] In spring, the first Monday in Lent (Quadrigesima) and Easter Eve were frequent days for such bonfires. In May, among the Franks of the Main, the unmarried women, naked and adorned with flowers, danced on the Blocksberg before the men, as described by Herbels in the tenth century.[139] In the central highlands of Scotland the Beltane fires were kindled on the 1st of May. Bonfires sometimes took place on Halloween (October 31st) and Christmas. But the great season all over Europe for these bonfires, then often held with erotic ceremonial, is the summer solstice, the 23d of June, the eve of Midsummer, or St. John's Day.[140]
