It is that wonderful time of the year where in
the Northern Hemisphere it is BELTANE and
in the Southern Hemisphere it is SAMHAIN,
below are some wonderful artworks inspired by
these two great times:

BELTANE:

Beltane (pronounced /ˈbɛltən/) is the anglicized spelling of Bealtaine or Bealltainn, the Gaelic names for either the month of May or the festival that takes place on the first day of May.

In Irish Gaelic the month of May is known as Mí Bealtaine or Bealtaine and the festival as Lá Bealtaine ('day of Bealtaine' or, 'May Day'. In Scottish Gaelic the month is known as either (An) Cèitean or a' Mhàigh, and the festival is known as Latha Bealltainn or simply Bealltainn. The feast was also known as Céad Shamhain or Cétshamhainin from which the word Céitean derives.

As an ancient Gaelic festival, Bealtaine was celebrated in Ireland, Scotland and the Isle of Man. There were similar festivals held at the same time in the other Celtic countries of Wales, Brittany and Cornwall. Bealtaine and Samhain were the leading terminal dates of the civil year in Ireland though the latter festival was the most important. The festival survives in folkloric practices in the Celtic Nations and the Irish diaspora, and has experienced a degree of revival in recent decades.

SAMHAIN:

The Samhain celebrations have survived in several guises as a festival dedicated to the harvest and the dead. In Ireland and Scotland, the Féile na Marbh, the 'festival of the dead' took place on Samhain.

The night of Samhain, in Irish, Oíche Shamhna and Scots Gaelic, Oidhche Shamhna, is one of the principal festivals of the Celtic calendar, and falls on the 31st of October. It represents the final harvest. In modern Ireland and Scotland, the name by which Halloween is known in the Gaelic language is still Oíche/Oidhche Shamhna. It is still the custom in some areas to set a place for the dead at the Samhain feast, and to tell tales of the ancestors on that night.

Traditionally, Samhain was time to take stock of the herds and grain supplies, and decide which animals would need to be slaughtered in order for the people and livestock to survive the winter. This custom is still observed by many who farm and raise livestock because it is when meat will keep since the freeze has come and also since summer grass is gone and free foraging is no longer possible.

Bonfires played a large part in the festivities celebrated down through the last several centuries, and up through the present day in some rural areas of the Celtic nations and the diaspora. Villagers were said to have cast the bones of the slaughtered cattle upon the flames. In the pre-Christian Gaelic world, cattle were the primary unit of currency and the center of agricultural and pastoral life. Samhain was the traditional time for slaughter, for preparing stores of meat and grain to last through the coming winter. The word 'bonfire', or 'bonefire' is a direct translation of the Gaelic tine cnámh. With the bonfire ablaze, the villagers extinguished all other fires. Each family then solemnly lit its hearth from the common flame, thus bonding the families of the village together. Often two bonfires would be built side by side, and the people would walk between the fires as a ritual of purification. Sometimes the cattle and other livestock would be driven between the fires, as well.
