The thoughts of a Norse Heathen.

Midsommar/Midsummer.

Midsummer is usually celebrated near the Summer Solstice, around June 21st. Historically, bonfires were common for this time, and people would both dance around them and sometimes even through them, though it was usually the cattle which were driven through the fires as a purification measure. Like Maitag, this high day is often associated with love and fertility.

The Misdummer celebration today is a mix of both Christian and Norse/other pagan beliefs.

Maypole dance:
A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place.
Primarily found within the nations of Germanic Europe and the neighbouring areas which they have influenced, its origins remain unknown. It has often been speculated that the maypole originally had some importance in the Germanic paganism of Iron Age and early Medieval cultures, and that the tradition survived Christianization, although losing any original meaning that it had; however, more recent scholarship has found that the custom of the maypole arose in the context of medieval Christian Europe. It has been a recorded practice in many parts of Europe throughout the Medieval and Early Modern periods, although it became less popular in the 18th and 19th centuries. Today, the tradition is still observed in some parts of Europe and among European communities in the Americas. The Maypole dance was almost definitely a fertility rite meant to symbolize the union of the masculine and feminine, which is a major theme in May Day celebrations across the historical Pagan footprint.

The pole is made from a young tree, cut down when its trunk reached the proper height for performing its duties as a Maypole. The pole, as you may have guessed, is the masculine part of the equation for this springtime tradition. Then, during the festivities, villagers would dance around the pole, weaving through each other while wrapping the Maypole in ribbon and foliage. Those would be the feminine qualities in the hopes of bringing fertility to the livestock, the land, and the people living off of it.
