2. The name Al Jauzah could possibly mean 'the Walnut', a translation which I think more to the point than 'the Giant', because in the beginning - the probable location of Orion - it should begin with something little and round (as for instance a top-knot, tikitiki):

The pair of joined hemispheres of a walnut can serve as a model for the 'cap' above and the 'cup' below, with level land to live on in the middle. However, people living on the islands in the Pacific might rather have chosen the more familiar bivalves found on the beaches.

The origin of the word jauzah - if we could belive in such a thing as the origin of a word - is though disputed:

"In early Arabia Orion was Al Jauzah, a word also used for stars in Gemini, and much, but not very satisfactorily, discussed as to its derivation and meaning in its stellar connection. It is often translated Giant, but erroneously, for it, at first, had no personal signification.

Originally it was the term used for a black sheep with a white spot on the middle of the body, and thus may have become the designation for the middle figure of the heavens, which from its preëminent brilliancy always has been a centre of attraction.

Some think that the Belt stars, δ, ε, and ζ, known to the Arabs as the Golden Nuts, first bore the name Jauzah, either from another meaning of that word, - Walnut, - or because they lay in the centre of the splendid quadrangle formed by α, β, γ, and ĸ; or from their position on the equator, the great central circle; the title subsequently passing to the whole figure.

Grotius adopted the first of these derivations, quoting from Festus the passage quasi nux juglans, that a lesser light, Robert Hues, thus enlarged upon:

Now Geuze signifies a Wall-nut; and perhaps they allude herein to the Latine word Jugula, by which name Festus calleth Orion; because he is greater than any of the other Constellations, as a Wall-nut is bigger then any other kind of nut." (Allen)

In my Latin dictionary iuglans is indeed explained as the walnut tree, and, furthermore, the word comes from Jovis glans which means the 'acorn' of Jupiter. This idea could agree with the position of the planetary sign of Jupiter in the Babylonian zodiac, on the ecliptic and at the straight vertical line which once could have defined the Tree:

At the bottom is Eridu (Canopus) followed by Ninmah with a little child.
