St Swithun’s day if thou dost rain
For forty days it will remain
St Swithun’s day if thou be fair
For forty days ’twill rain no more
And the day is today, July 15. In Tory Historian's part of the world the sun is shining so the prediction is good, though, apparently, the weather is not too good in Scotland.
This is rather a charming and informative piece for young children on the subject that even explains how the legend came about.
A legend says that as the Bishop [St Swithun, Saxon Bishop of Winchester] lay on his deathbed, he asked to be buried out of doors, where he would be trodden on and rained on. For nine years, his wishes were followed, but then, the monks of Winchester attempted to remove his remains to a splendid shrine inside the cathedral on 15 July 971. According to legend there was a heavy rain storm either during the ceremony or on its anniversary.Served those monks right, says Tory Historian.
