"We are forced to admit that whatever the outside evidence, the direct evidence of the buildings themselves points logically and inexorably to only one conclusion: the Sicilian architect was acquainted with the principle of the truss, and employed it regularly from about 550 onwards.
The objections to this view are obvious. The chief one is that Sicilian architecture is so imitative and backward relative to that of the mainland that it seems incredible that it could invent for itself a principle so complex; and knowledge of the truss was certainly not, at that date, derived from Greece. This is the dilemma that has tormented many scholars: how could the Sicilians know about the truss if the Greeks did not?"
"The wood of the silver-fir may be called the stongest of all. But for the carpenter's purposes fir best takes glue because of its open texture and the straightness of its pores; for they say that it never by chance comes apart when it is glued."
"But largest of all, they say, are the trees of Corsica; for whereas silver-fir and fir grow in Latium to a very great size, and are taller and finer than the silver-firs and firs of south Italy, these are said to be nothing to the trees of Corsica."
