I've seen "Carmen Glaciei Ignisque", but I have some doubt with the use of genitive here.
Can someone help me find examples from classical works that support the use of genitive?
Or find an explanation in a grammar book, since I can't seem to find a fitting one. It's not possessive genitive, partitive, genitive of quality, of material...
Do you think "Carmen de Glacie Igneque" will work?
Stuff I've found so far:
*I'm not sure about the date, since I guess titles may be added a lot later, and some are for Greek works.
Carmen de Duobus Populis
Carmen De Moribus
Carmen Fratrum Arvalium (performed by Fratres Arvales)
Carmen Saliorum (performed by Salii)
Carmen Naupactium (attributed to a Naupactus)
*Carmen Nelei (about Neleus)
"In Carmine Priami quod est" (probably about Priamus) - Varro
"et in Nelei Carmine" - Varro
It looks like Nelei Carmine/Carmen Nelei supports using genitive.
Another pro genitive:
"ut a Naeuio narratum est in carmine belli Punici"
I think I have enough reason to believe it's OK to use genitive in this case, although I have the feeling that these authors chose genitive for a shorter and more concise name to refer to a work, also more casual perhaps.
