“ In the provinces the quaestors had the same jurisdiction as the curule aediles at Rome. The relation existing between a praetor or proconsul of a province and his quaestor was, according to ancient custom, regarded as resembling that between a father and his son. When a quaestor died in his province, the praetors had the right of appointing a proquaestor in his stead; and when the praetor was absent, the quaestor supplied his place, and was then attended by lictors. ”
