Casus Fabulae Romanae I is an unusual book in that it combines two books into one graphic novel. As such, it requires the instructor manuals from both of the original books. This set includes the Casus Fabulae Romanae I student book, the Ecce Caecilia et Verus instructor manual, and the Caecilia et Verus in Foro Romano instructor manual, all offered at a discounted price.
