Strabo Geography 4.5.2

[2] There are four passages commonly used from the continent to the island, namely, from the mouths of the rivers Rhine, Seine, Loire, and Garonne; but to such as set sail from the parts about the Rhine, the passage is not exactly from its mouths, but from the Morini, ¹ who border on the Menapii, ² among whom also is situated Itium, ³ which divus Caesar used as his naval station when about to pass over to the island: he set sail by night, and arrived the next day about the fourth hour, ⁴ having completed a passage of 320 stadia, and he found the corn in the fields. The greatest portion of the island is level and woody, although many tracts are hilly. It produces corn, cattle, gold, silver, and iron, which things are brought thence, and also skins, and slaves, and dogs sagacious in hunting; the Kelts use these, as well as their native dogs, for the purposes of war. The men are taller than the Kelts, with hair less yellow; they are slighter in their persons. As an instance of their height, we ourselves saw at Rome some youths who were taller than the tallest there by as much as half a foot, but their legs were bowed, and in other respects they were not symmetrical in conformation. Their manners are in part like those of the Kelts, though in part more simple and barbarous; insomuch that some of them, though possessing plenty of milk, have not skill enough to make cheese, and are totally unacquainted with horticulture and other matters of husbandry. There are several states amongst them. In their wars they make use of chariots for the most part, as do some of the Kelts. Forests are their cities; for having enclosed an ample space with felled trees, they make themselves huts therein, and lodge their cattle, though not for any long continuance. Their atmosphere is more subject to rain than to snow; even in their clear days the mist continues for a considerable time, insomuch that throughout the whole day the sun is only visible for three or four hours about noon; and this must be the case also amongst the Morini, and the Menapii, and among all the neighbouring people.
