Sharada Sampat for Hindus, fall (Sampat), beginning of winter (Sharada), the period of paters (Pitris - Pitriyana), menes, ancestors, for Indian Aryans, Vishuvan day. Yeah, in way-back-history, perhaps the beginning of the year.
Why? Doesn't it look like Somerset, UK? I was at Stonehenge last week .. saw plenty of yogis [ no .. not bears! ]
Sadly the original Glastonbury Thorn was cut down and burned as a relic of superstition during the English Civil War, another was planted on Wearyall Hill in 1951 to replace it, but has been vandalised often since, cut down, I think in 2010, and the stump removed in 2019. The original tree has been propagated several times, with one tree growing at Glastonbury Abbey and another in the churchyard of the Church of St John.
