Beltane is the last of the three spring fertility festivals. Beltane is the second principal Celtic festival (the other being Samhain). Celebrated approximately halfway between spring equinox and the midsummer (Summer Solstice). Beltane traditionally marked the arrival if summer in ancient times.
At Beltane the Pleiades star cluster rises just before sunrise on the morning horizon. The Pleiades is a cluster of seven closely placed stars, the seven sisters, in the constellation of Taurus, near his shoulder. When looking for the Pleiades with the naked eye, remember it looks like a tiny dipper-shaped pattern of six moderately bright star in the constellation of Taurus. It stands very low in the east-northeast sky for just a few minutes before sunrise.
Beltane, and its counterpart Samhain, divide the year into its two primary seasons, winter (Dark Part) and summer (Light Part). As Samhain is about honouring Death, Beltane is about honouring Life. It is the time when the sun is fully released from his bondage of winter and able to rule over summer and life once again.
It is a time of "no time" when the veils between the two worlds are at their thinnest. No time is when the two worlds intermingle and unite and the magic abounds! It is the time when the Faeries return from their winter respite, carefree and full of faery mischief and faery delight. On the night before Beltane, in times past, folks would place rowan branches at their windows and doors for protection, many otherworldly occurrences could transpire during this time of "no time". Traditionally on the Isle of Man, the youngest member of the family gathers primroses on the eve before Beltane and throws the flowers at the door of the home for protection. In Ireland it is believed that food left over from May Eve must not be eaten, but rather buried or left as an offering to the faery instead. Much like the tradition of leaving of whatever is not harvested from the fields on Samhain,
