Note 29 — Chapter I

Cum ipsi se —— formarent, tum finitimi etiam, etc. Some of the editors of Livy have remarked on this passage, that cum when answering to tum may be joined to a subjunctive, as here; the fact however is, that cum here does not answer to tum at all; cum is here "whilst,"—and so necessarily requires the verb to be in the subjunctive mood.
