Bateman explains the diagram thus:
- A and B be the Axeltrées, when the ſéeing direct lye beholdeth the poynt, C. when it beholdeth the point D. Then theſe two B C procéeding from the eyes, be called axeltrees, for they procéede immediatelye from the eyes, by meane to the thing ſeene. The third is diſtance proportional. The fourth D C is a certaine ſtede or place, not too farrre from the lyne of the ſight.
"Axeltree" here is simply "axis" in Bartolomeus's Latin. One of the meanings of "axis" in Latin is an axle, and in Bateman's time, when it was made of wood, this was called an axletree.
