Note 2686 — PORTUS ITIUS
Reading edition
It has been argued that commodissimum in this passage means not ‘most convenient’, but simply ‘very convenient’. I have not the slightest doubt that the former is the right interpretation, just as in B. G., iv, 21, § 3, brevissimus (in Britanniam traiectus) unquestionably means ‘the shortest’, and not ‘a very short’ (passage to Britain): but if I were wrong my mistake would be unimportant. It will hardly be denied that if Caesar had found a port from which the passage was more convenient than from the Portus Itius, he would have chosen it. See p. 574, infra.
