Casiri translates the original testimony of the historian
Rasis, as it is alleged in the Arabic Biographia Hispanica,
pars ix. But I am most exceedingly surprised at the
address, Principibus caeterisque Christianis, Hispanis suis
Castellae. The name of Castellae was unknown in the viiith
century; the kingdom was not erected till the year 1022, a
hundred years after the time of Rasis, (Bibliot. tom. ii. p.
330,) and the appellation was always expressive, not of a
tributary province, but of a line of castles independent of
the Moorish yoke, (D'Anville, Etats de l'Europe, p. 166 -
170.) Had Casiri been a critic, he would have cleared a
difficulty, perhaps of his own making.]
