Full marks to Grendolino with this great example of The Seven Sisters star symbols better known as Pleiades or M45. Ref A above refers to much of the background at web on the star system and mythology. The German blade makers applied much Talisman for effect from astrology mainly the sun often with eyes nose mouth accompanied by fanciful rays.. and funniface moons. Peter Munch (Solingen)is credited with these under his name but a footnote also suggests these were not sword makers marks but applied purely as Talisman and quite at random. What may be seen on typical blades at thread are occasional locally applied marks perhaps to raise the price? On the other hand trade blades in the typical profile with heavy back blade and three deep fullers may well all originally have been star marked in Solingen. Other weapons must have also been so stamped...see below.
What is certain about the silver decoration on the example scabbard is its Yemeni origin as this is typical sand cast low quality silver often seen on Yemeni work.
Jim...Regarding the Big Dipper...The Plough or The Great Bear ...URSA MAJOR … I have avoided that but note its Chinese name and as you say the 7 wells etc and will place a post covering that situation but just to keep the two so called seven star constellations separate for the moment...
