Boethius, On Geometry (with other geometrical works)

This biblical reference points to the verse: "lest there should be among you man or woman, or family or tribe, whose heart turneth away this day from the Lord our God, to go and serve the gods of those nations." It serves as a moral preamble to the mathematical rigor that follows.

Boethius' Geometry

... as the geometria geometry is known to be the discipline of observing magnitude, it must first establish the nature of the point, the line, and the surface. For the point is that which has no parts, and the line is a length without breadth.

The definition of the line according to Euclid.

Furthermore, the superficies surface is that which possesses only length and breadth. When these three elements are understood, the mind may then ascend to the consideration of solid bodies. This science, handed down by the ancients, allows the practitioner to measure the hidden dimensions of the earth and the heavens, thereby reflecting the order of the divine creator in the structure of the world.
