syllepsis (from Silva Rhetoricae, an interesting site with a complete index of rhetorical terms)
When a single word that governs or modifies two or more others must be understood differently with respect to each of those words. A combination of grammatical parallelism and semantic incongruity, often with a witty or comical effect. Not to be confused with zeugma.

Ovid practiced syllepsis, especially in the Metamorphoses, together with personification, as is discussed by Philip Hardie in the chapter "Ovid and early imperial literature" (Part II of "Context and History") in The Cambridge Companion to Ovid.
