London - A silvery sliver of a cirrus cloud filament complete with feathery down-arching end curls blazed a trail at sunset tonight across the waxing Harvest Moon.
The dazzling spectacle exactly mirrored the ancient Egyptian Book of the Dead's Winged Sun of Thebes, a potent symbol of the eternal soul later adopted by Harley Davidson in their iconic Live To Ride logo.
Viewed circa 8pm from the top of Parliament Hill the lunar lightshow's reflection was shimmering brilliantly in the darkening waters of the Ladies Pond as local Wiccans gathered ahead of Saturday's skyclad Last Night Of The Proms.
"Hampstead's notorious for this sort of thing," lunar lore naturist Helga Smothaclees from the Tanza Road LGBT Collective tweeted from her patio, "because it straddles ancient ley lines bursting with cosmic activity... like tonight's awesome omen."
Curiously enough the lunar winged disc also appears in a stained glass window at a local Greek restaurant called The Mount Olympus whose upstairs function room serves as the Collective's regular Friday night meeting place.
The ancient Greeks depicted the winged disc as the 'knob of the Staff of Hermes' - a heraldic staff associated with the messenger for the gods and 'conductor of the dead and protector of merchants and thieves' if the papyri are to be believed.
The Summer Triangle will just be visible in the southern sky around midnight, especially from high up in Canary Wharf.
