Note 13 — Chapter XXV

Et quia strepitus Rotomagi, quæ populosa civitas est, intolerabilis erat ægrotanti, extra urbem ipse rex præcepit se aufferi, ad ecclesiam Sancti Gervasii, in colle sitam occidentali; Ordericus Vit. vii. 656. A priory was attached to the church of St. Gervais, which furnishes probably the oldest ecclesiastical remain in Normandy. The crypt, below the apsis represented in the cut at the foot of this chapter, is supposed to be Roman, and coeval with the earliest introduction of Christianity at Rouen. The apsis itself is probably a re-erection with the original materials, but anterior to Duke William.
