"I'll have un, I'll have un, I'll have un, What have'e, What have'e, What have'e, What will'e, What will'e, What will'e, Onec, Onec, Onec, O'hurro, O'hurro, O'hurro." As this rhyme was repeated, all the harvesters stood round the farmer in a circle, whilst he waved a sheaf in the air. This custom of mourning the dead God of vegetation was very widely spread over the world.[3] No one who has heard the mournful strain in which this chant of our ancient harvest fields was sung can doubt that in its original use it was a song of mourning. The Celtic Priests or Druids knew a good deal of rude astronomy. They used the stone circles, so many of which still survive, for purposes of astronomical observations. By watching the alignment of the sun at rising or setting, and also of certain stars, with the centre stone and some stone on the circumference of the circle, they were able to calculate the seasons of the year and the dates of their festivals. Until a generation ago one of these ancient circles stood on Trewarvas Head; it was pulled down by some foolish and ignorant people who thought they might find hidden treasure under the great stones. From the top of the high cliff overlooking the sea the Druid Priests would have a splendid view of the far horizon. We can picture them making their observations through the silent hours of some still star-lit night, with the ceaseless slumbrous swell of the sea on the rocks far beneath them. On Midsummer Eve the Druids lit a great fire on the summit of Tregoning Hill. We know this, because the custom of lighting the fire survived until very recent times. An old woman deplored its discontinuance to the writer as a sign of the prevailing irreligion of the times. It seems more than probable that at this Midsummer Festival human victims were sometimes sacrificed in honour of the sun. In the remote Highlands and Islands of Scotland this festival was observed down to the early part of the eighteenth century, in a way which clearly points to human sacrifice as the great central act of the rite.[4] Numbers of men were in the habit of gathering on Midsummer Eve in these remote parts of the kingdom round the ancient stone circles midst the hills. A fire was lighted in the centre of the circle; pieces of cake or bannock were then placed in some cavity where previously a blackened and burnt fragment of the cake had been placed. Each person, having first been blindfolded, then drew from the cavity a piece of the broken cake; the man unfortunate enough to draw the blackened fragment had to leap through the fire and pay a forfeit or fine. In the dim past the drawer of the blackened fragment doubtless became the victim offered to the God to ward off his anger from the community. This ancient rite must have been practised in our Parish more than a thousand years before the coming of Christ.
