On Roman land surveying.
'We are sorry to hear that a dispute (which is on the point of being settled by arms instead of by the law) has arisen between the Spectabiles Leontius and Paschasius as to the boundaries of their properties[320]. If they are so fierce against one another here in Italy, where there are mountains and rivers and the "arcaturae" [square turrets of the land surveyor] to mark the boundaries, what would they have done in Egypt, where the yearly returning waters of the Nile wash out all landmarks, and leave a deposit of mud over all?
'Geometry was discovered by the Chaldaeans, who perceived that its principles lay at the root of Astronomy, Music, Mechanics, Architecture, Medicine, Logic, and every science which deals with generals. This science was eagerly welcomed by the Egyptians, who perceived the advantage it would be to them in recovering the boundaries of estates obliterated by the wished-for deluge[321] of the Nile.
'Therefore let your Greatness send an experienced land surveyor (agrimensor) to settle this dispute by assigning fixed boundaries to the two estates.
'Augustus made a complete survey of the whole "Orbis Romanus," in order that each taxpayer should know exactly his resources and obligations. The results of this survey were tabulated by the author Hyrummetricus. The Professors of this Science [of land surveying] are honoured with a more earnest attention than falls to the lot of any other philosophers. Arithmetic, Theoretical Geometry, Astronomy, and Music are discoursed upon to listless audiences, sometimes to empty benches. But the land surveyor is like a judge; the deserted fields become his forum, crowded with eager spectators. You would fancy him a madman when you see him walking along the most devious paths. But in truth he is seeking for the traces of lost facts in rough woods and thickets[322]. He walks not as other men walk. His path is the book from which he reads; he shows what he is saying; he proves what he hath learned; by his steps he divides the rights of hostile claimants; and like a mighty river he takes away the fields of one side to bestow them on the other.
'Wherefore, acting on our instructions, choose such a land surveyor, whose authority may be sufficient to settle this dispute, that the litigants may henceforth cultivate their lands in peace.'
