St. John’s Eve Lore
At sunset on June 23rd, another of the ancient fire festivals begins and is known as St. John’s Eve. Not that long ago, it was a wide-spread tradition throughout Ireland that on St. John’s Eve a curious practice prevailed, in some districts, which related to the time-honoured tradition of lighting a bonfire.

Before sunset on St. John’s Eve a small fire was built and lit in a place that was near to the byre because in such a position the milk-cows would pass close to the fire as they returned from the fields. In fact, great care was taken to drive the cows as close as possible to the fire itself. This was done, it was said, to allow the cows to “smell” the fire, which it was believed would have a very beneficial effect on the quantity and the quality of the milk and butter produced. It was also believed to be a safeguard against any evil spirits or witchcraft which might befall the cow herself. Then, coals were taken from the little fire, and one of them is thrown into each field of potatoes that belong to the owner of the cow. Through this ritual, it was thought, a great increase in the cow’s production would be achieved..
It was the custom in some places that when a cow begins to calve the owner would place a “grape” (the ordinary steel fork used in farming operations) near her head until she “cleans” (Rids herself of the afterbirth). The steel or iron from which they form the grape was considered “lucky,” and effective defence against any evil influences spread by the fairy-folk. There may, of course, be other customs resorted to on such occasions as this, but what kind of results they achieve I couldn’t say. There is another custom where a silver coin is placed in the first drink that is given to the cow after it has calved, and the reason behind this curious custom was simply that it was considered “lucky to let the cowlick the silver.”
There are many other peculiar practices, such as tying a red rag to the tail of the milch-cow (Milk Cow), with a few horse-shoe nails, a partially burned coal, and some salt are rolled in the rag. It was quite common at one time to see red rags hanging from the tails of milch -cows at fairs in the west of Ireland, allowing the intending purchasers of milch-cows to easily recognise the milking cow, from the ones due to calve (‘springer’).
Tradition also advises farmers to take a very necessary precaution when the cow calves. Strangely this is to give the first of the milk, a small glassful is enough, to that very useful domestic animal, the cat. The reason behind this peculiar tradition, I have been told, is that they give the first of the milk to the cat so that the cat can take the bad luck away with her on her paws.
