Rh Asia; discēdĕrĕ ā Rhŏdănŏ to depart from the Rhone; in Nŭmĭdĭā essĕ to be in Numidia.

(2) All Common names : ā fŏrō from the Forum; in fŏro in the Forum.

So with urbs, oppĭ dum, when in Apposition to Proper names : ĭn oppĭdum Cirtam to the town Cirta; ex urbĕ Rōmā from the city of Rome; Nĕāpŏlī ĭn cĕlĕberrĭmō oppĭdō at Naples, a most populous town.

(3) A Preposition must be used if the neighbourhood of a town is meant: ăd Brundĭsĭum flexĭt ĭtĕr he bent his way towards Brundisium; Caesăr ā Gergovĭā discēssissĕ dīcebātūr 'Cæsar was said to have gone away from (the walls of) Gergovia.

§ 331 With —(1) With denoting the Instrument, is expressed by the simple Ablative, Poenōs ĕquĭtātū dissĭpăt he scatters the Carthaginians with his cavalry:

(2) With meaning together with, and denoting the Accompaniment, is expressed by cum (with the Abl.), cum ĕquĭtātū vĕnĭt he comes with his cavalry, cum febrĕ rĕdĭīt he returned with a fever.

(3) With denoting the manner, is expressed by the Abl. if an epithet is added, otherwise by cum with Abl., see §321*. But it must be often translated by an Adverb, as cautē ăgĕrĕ to act with caution.

§ 332. 'opŭs est, ūsŭs est.— ŏpŭs est there is need, lit. there is work, takes a Dat. of the Person needing. The construction of the thing needed is as follows:

Either (A) ŏpŭs is the Predicate, and what is needed the Subject: nōbīs dux ŏpŭs est a leader is what we want (lit. the work for us). Hence with an Infin. of actions: glōrĭārī nōn ŏpŭs est there is no need to boast (boasting is not the work). Or (B) ŏpŭs is the Subject, and what is needed is put in the Abl. of the Instrument: glădĭō ŏpŭs est there is need of the sword (lit. work to be done by the sword). So of Actions with the Perf. Part., especially the Neut. Part, used Impersonally, prŏpĕrātō ŏpŭs est there is need to haste (lit. work to be done by hurrying). See § 368.
