Bruce checks his chronology by an eclipse which took place in 1553, and
which the Abyssinian chronicle assigns to the 13th year of Claudius. This
alone would be scarcely satisfactory as a basis for the retrospective
control of reigns extending through nearly three centuries; but we find
some other checks.
Thus in Quatremere's Makrizi we find a correspondence between Sultan
Bibars and the King of Habasha, or of Amhara, Mahar AMLAK, which
occurred in A.H. 672 or 673, i.e. A.D. 1273-1274. This would fall within
the reign of Icon AMLAK according to Bruce's chronology, but not according
to Salt's, and a fortiori not according to any chronology throwing the
reigns further back still.
In Quatremere's Egypte we find another notice of a letter which came to
the Sultan of Egypt from the King of Abyssinia, IAKBA SIUN, in Ramadhan
689, i.e. in the end of A.D. 1289.
Again, this is perfectly consistent with Bruce's order and dates, but not
with Salt's.
The same work contains a notice of an inroad on the Mussulman territory of
Assuan by David (II.), the son of Saif Arad, in the year 783 (A.D.
1381-1382).
In Rink's translation of a work of Makrizi's it is stated that this same
King David died in A.H. 812, i.e. A.D. 1409; that he was succeeded by
Theodorus, whose reign was very brief, and he again by Isaac, who died in
Dhulkada 833, i.e. July-August 1430.
