4We are certain that buildings were thus originally constructed, from the present practice of uncivilized nations, whose buildings are of spars and thatch, as may be seen in Gaul, in Spain, in Portugal, and in Aquitaine. The woods of the Colchi, in Pontus, furnish such abundance of timber, that they build in the following manner. Two trees are laid level on the earth, right and left, at such distance from each other as will suit the length of the trees which are to cross and connect them. On the extreme ends of these two trees are laid two other trees transversely: the space which the house will inclose is thus marked out. The four sides being thus set out, towers are raised, whose walls consist of trees laid horizontally but kept perpendicularly over each other, the alternate layers yoking the angles. The level interstices which the thickness of the trees alternately leave, is filled in with chips and mud. On a similar principle they form their roofs, except that gradually reducing the length of the trees which traverse from angle to angle, they assume a pyramidal form. They are covered with boughs and smeared over with clay; and thus after a rude fashion of vaulting, their quadrilateral roofs are formed.
4That houses originated as I have written above, we can see for ourselves from the buildings that are to this day constructed of like materials by foreign tribes: for instance, in Gaul, Spain, Portugal, and Aquitaine, roofed with oak shingles or thatched. Among the Colchians in Pontus, where there are forests in plenty, they lay down entire trees flat on the ground to the right and the left, leaving between them a space to suit the length of the trees, and then place above these another pair of trees, resting on the ends of the former and at right angles with them. These four trees enclose the space for the dwelling. Then upon these they place sticks of timber, one after the other on the four sides, crossing each other at the angles, and so, proceeding with their walls of trees laid perpendicularly above the lowest, they build up high towers. The interstices, which are left on account of the thickness of the building material, are stopped up with chips and mud. As for the roofs, by cutting away the ends of the crossbeams and making them converge gradually as they lay them across, they bring them up to the top from the four sides in the shape of a pyramid. They cover it with leaves and mud, and thus construct the roofs of their towers in a rude form of the “tortoise” style.
