[Footnote 68: The historians of Mahomet, Abulfeda (in Vit.
Mohammed, p. 92, 93) and Gagnier, (Vie de Mahomet, tom. ii.
p. 247,) date this embassy in the viith year of the Hegira,
which commences A.D. 628, May 11. Their chronology is
erroneous, since Chosroes died in the month of February of
the same year, (Pagi, Critica, tom. ii. p. 779.) The count
de Boulainvilliers (Vie de Mahomed, p. 327, 328) places this
embassy about A.D. 615, soon after the conquest of
Palestine. Yet Mahomet would scarcely have ventured so soon
on so bold a step.]
