Solstice

And while they were all standing round them, Merlin came up to them and said, "Now try your forces, young men, and see whether strength or art can do the most towards taking down these stones." At this word they all set to their engines with one accord, and attempted the removing of the Giant's Dance. Some prepared cables, others small ropes, others ladders for the work, but all to no purpose. Merlin laughed at their vain efforts, and then began his own contrivances. When he had placed in order the engines that were necessary, he took down the stones with an incredible facility, and gave directions for carrying them to the ships, and placing them therein. This done, they with joy set sail again, to return to Britain; where they arrived with a fair gale, and repaired to the burying-place with the stones. When Aurelius had notice of it, he sent messengers to all parts of Britain, to summon the clergy and people together to the mount of Ambrius, in order to celebrate with joy and honour the erection of the monument. Upon this summons appeared the bishops, abbats, and people of all other orders and qualities; and upon the day and place appointed for their general meeting, Aurelius placed the crown sepulchre upon his head, and with royal pomp celebrated the feast of Pentecost, the solemnity whereof he continued the three following days.

It's interesting that the old story revolves around Pentecost, almost the right hour for the summer solstice. The winter has begun, and the time of fire now begins its height. It'll be cold tonight. Keep your loved ones close.
