The paper contextualises the occurrences of the iunctura castra sequi in three elegiac Latin poems (Prop. 2.10.19, Tib. 2.6.1 and Ov. am. 3.8.26), with the addition of two further passages (Verg. ecl. 10.23 and Lucan. 2.348): these latter ones, indeed, though belonging to different eidetic contexts, exhibit important links to characteristically elegiac topoi. In all of the passages under consideration, castra sequi reveals itself, so to say, as a marker of the crucial dichotomy between love and war, militia and amor, which can only find some sort of recomposition via the metaphorical plexus of militia amoris.
