Recently, claims have been coming to light that a lot of exotic inventions really came from Britain; first we had
the mediæval English origins of curry, and
the Scottish origins of the Afro-American musical tradition. And now a popular history author wants to add
the boomerang to the list of British inventions, on the strength of rock carvings in the West Yorkshire moors depicting four-armed boomerangs. (Mainstream archæologists, however, believe that the swastika-like design was merely a common motif in Greek and Roman mythology.) Do you suppose that the contemporary two-armed design came about to make them more compact and easier to ship from England to Australia?
(Hmmm; someone should do up "historical" boomerangs made of brass or porcelain or somesuch and adorned with British imperial designs; lions, cannon, Union Flags, and such, which, in this alternate universe, could have been issued to British explorers.)
