Although similar to the gloaming, grimmelings is a slightly different natural phenomenon at both ends of the rotating sun’s traverse across the sky.
Grimmelings – The first or last gleams of the day (Scots, esp. Orkney).
From the Norwegian “grimla”, to glimmer before the eyes, to twinkle or blink. Also “grimlins”.
Or “the harlot’s hour”: “Just in the close and shutting up of day, When the last gleams were hurrying swift away; The harlots hour their subtle trains to lay” Robert Gould’s 1689 Paraphrase of Proverbs 7 (KJV has “in the twilight, in the evening, in the black and dark night”)

I’ve heard this time being called the golden hour before, from a photography point of view, but not the harlot’s hour!

Yes, I love that expression, the harlots hour, who knew that in the olden days they came out during this time, very interesting. Perhaps maybe they capitalised on the soft and kind light that renders everything beautiful.

I love that idea, and there might be something in it — you’ve heard of the expression ‘mutton dressed as lamb’? I just came across the term Mutton Shunter the other day, from another blog I follow https://www.sillyoldsod.com/mutton-shunter/ Maybe they were busy in those harlots hours, too?

Oh my gosh…what a cool blog..that guy – Silly Old Sod, he doesn’t take himself too seriously, and that post was very good. I have subscribed! I have found a similarly old book from Edwardian times about ladies of the night and all of the slang that goes along with that. I have been meaning to do a post on it, I just having got around to it. Such amazing and colourful words, I wish they were around nowadays hey
