116. A Coin of Khalif ʿAbd al Malik, 694-5 AD, Umayyad, Coll. of R. W. Morris (Kou); B. Umayyad dirham, American Numismatic Society.
Vol. 1 p22: The great majority of art sources, however, portray swords that have tips that are either so rounded as to make a thrusting blow impossible or are so regularly broad along their length as to be clearly designed for cut rather than thrust. In the 7th century (Figs. 111, 112, 113, 114, 116 and 141), 8th century (Figs. 118, 102 and 470), 9th century (Figs. 143, 202, 447 and 502), 10th century (Figs. 213A, 316, 317, 347, 350, 354, 496, 505 and 507) and 11th century (Figs. 153, 194, 361, 363, 497, 499, 517 and 597) these forms of sword clearly predominated throughout the Muslim world.
Vol. 2 p.346: Finally, one may note a slight preference for baldrics, as already suggested by the written sources (Figs. 116, 122 and 124).
