The cacata -acrostic ( Ecl . IV 47-52) is considered accidental, as being inconsistent with the dignitas of this “Messianic” Eclogue . It is however possible to demonstrate that Virgil employs such acrostics on other occasions with the object of undercutting such political panegyric. The intentionality of this cacata -acrostic is further buttressed by clues in the lines it spans as well as by winks tipped in other parts of the poem. Pointers to this acrostic are also embedded in the foregoing third Eclogue , especially in the section devoted to Pollio, dedicatee of Eclogue IV. Problematic passages in both these Eclogues are elucidated by the presence of the cacataacrostic.
