The contents of the first quaternion of Amiatinus coincide so remarkably with descriptions of the celebrated Codex Grandior of Cassiodorus that it has been supposed that the leaves were transferred from it bodily; the conjecture has been rendered more credible by the fact that this codex was actually seen in England by Bede, perhaps before Amiatinus was carried to Rome.
内容的第一次四元的amiatinus不谋而合,所以显描述著名法典grandior的cassiodorus称,它一直以为叶均被转移到它的身体;猜想已变得更为可信的事实,即这一法典,是我们实际上所看到的在英格兰,由贝代,或许之前amiatinus进行了罗马。
