Salve!
Can you post the bit that stimies you?
As for the use of "magna" as a neuter noun in the plural, that might be possible. I did a full-text search for "magna" as a neuter noun (finding nom. and acc. plural) in the
Latin Library-texts of Livy's
Ab urbe condita and Caesar's
De bello Gallico. I found two occurrences that might fit the bill:
- Livy, Book II: "Quattuor et uiginti lictores apparere consulibus et eos ipsos plebis homines; nihil contemptius neque infirmius, si sint qui contemnant; sibi quemque ea magna atque horrenda facere."
- Livy, Book IV: "Desineret ergo mirari cur nemo de commodis plebis ageret; eo impendi laborem ac periculum unde emolumentum atque honos speretur; nihil non adgressuros homines si magna conatis magna praemia proponantur"
- Livy, Book XXXVII: "Ea, quae legato magna ad pacem impetrandam uidebantur, parua Romanis uisa" (although this example is not strictly what you're looking for)
- Livy, Book ??: "Potiemur praeterea cum pulcherrima opulentissimaque urbe tum opportunissima portu egregio unde terra marique quae belli usus poscunt suppeditentur; quae cum magna ipsi habebimus tum dempserimus hostibus multo maiora." (not sure about this one)
- Livy, Book XXXIII: "Adiecta etiam illa uox, bono animo esse regem ut iuberet, quae maxime Aetolos offendit iam tumentes querentesque mutatum uictoria imperatorem: ante pugnam omnia magna paruaque communicare cum sociis solitum, nunc omnium expertes consiliorum esse, suo ipsum arbitrio cuncta agere" (not sure abut this one either)
I did the same search for Caesar's "de bello Gallico". But there were no occurrences of "magna" as a plural noun.
Relates searches:
Search for "magnorum" in Livy's "Ab urbe condita"
- No occurrences as a genitive plural substantive, only 3 occurrences as an adjective: 2 x "bellorum magnorum", 1 x "magnorum imperatorum"
Search for "magnorum" in Caesar's "de bello Gallico"
Search for "magnum" in Livy's "Ab urbe condita":
- Book XXIII: "magnum [ausuram] facinus" (as an adjective!)
Search for "magnum" in Caesar's "de bello Gallico"
Livy uses "magna" several times together with "res", e.g.:
- Livy, "Ab urbe condita", Book I: "Namque Proculus Iulius, sollicita civitate desiderio regis et infensa patribus, gravis, ut traditur, quamuis magnae rei auctor in contionem prodit."
- Livy, Book III: "In exercitu Romano cum duo consules essent potestate pari, quod saluberrimum in administratione magnarum rerum est, summa imperii concedente Agrippa penes collegam erat"
- Livy, Book XXV: "Rem se ait magnam incohasse, ad quam perficiendam ipsius Gracchi opera opus esse"
- Livy, Book XXXI: "Quod si tantum militum Romanorum fuisset ut et Chalcis teneri et non deseri praesidium Athenarum potuisset, magna res principio statim belli, Chalcis et Euripus adempta regi forent"
All in all, even "magna" is used fairly seldom. Of course I checked only Livy (a few occurrences) and Caesar (none). One probably could check Cicero, but there a far too many files to do that quickly. I hope that this helps you.
