Hi Rod,
Thank you the response and excellent information. With your reference to the Afar, it prompted me to recheck Burton ("book of the Sword", p.164-65) where he refers to the 'Dankali' (Danakil, which is also the term for the Afar region of Ethiopia). On the same page in fig.177 he shows a 'smaller Abyssinian blade' shotel with similar shallow recurve and median ridge blade profile as seen on the discussed example.
Interestingly on p.165, Burton shows an illustration on what is clearly a kaskara and is captioned 'Dankali sword'.
The kaskara of course is from the Sudan, however is well known among Eritrean weapons, and Ethiopian in degree, which would include Danakil or Afar regions.
The diffusion of weapons in these regions is well established, and clearly while certain forms are more distinctly seen with certain tribes and regions, a degree of use of the weapons of congruent regions is to be expected. It seems quite reasonable that the Afar would have used shotels with these blades, and in limited degree so that illustrations or direct association would be unlikely. I think your suggestion of possible use of these by Afar tribes near the Ethiopan regions you note is well placed and quite likely.
It seems that shotels with this shallow recurved blade were in existence at the time of Burton's research, well before 1884 so probably as early as mid 19th century, so the period of such blade form is established. With the Afar provenance, those tribes as well as those of northern Ethiopian regions may be considered in those who might have used them, and it would seem the form continued in use well into the 20th century.
I'm still hoping those who have collected Ethiopian weapons will follow the lead and contribute examples of the early sickle form shotel as well as those with trade blades of sabre form (Wilkinson, Solingen) and possibly gurades.
Thank you very much Rod !
All very best regards,
Jim
