Now concerning the Kings which ruled over certain Cities in Gallia the same Author makes mention of them in very many Places; Out of which this is particularly worthy our Observation: That it was the Romans Custom to caress all those Reguli whom they found proper for their turns: That is, such as were busy men, apt to embroil Affairs, and to sow Dissentions or Animosities between the several Commonwealths.
