Still more interesting is that Thomas' attack on Siger and Tempier's attack on Averroists had had its pre-history which proves that the combat against Averroists had in fact its roots in the rift between Franciscan and Dominican views and that certain of Thomas's propositions (his clinging to creatio in theology and his concession to eternity in philosophy), together with their more or less supposed Averroism, had exactly been in the backsight of Franciscan friars (among these of Bonaventure) before the escalation of events in the 1270s (Gilson 2006:26-30).

Needless to say, for the practical purpose of laying a foundation, some sort of sightline on the ground would have to have been established, perhaps using a front and backsight of some kind, but as a means of gauging the location of the pole the kind of device I am positing could conceivably have been employed.
