 pears in only one other place in Vitruvius, 64, 20, terminavi finitionibiis, 

 "I have defined the limits" ; but ef. Cic. Fin. 1, 46, ipsa natura diritias 

 . . . et parabiles et terminatas. Further light on the meaning of the 

 verb mav be sot from the use of the substantive terminatio, which oc- 

 curs thirteen times in Vitruvius. In five of these it means "limits" 

 (36, 24, finire terminationibus, cf. 64, 20, terminavi finitionibus just 

 quoted above; 28, 8; 67, 20; 112, 6; 113, 21); "end" in 103, 13;
