Amburbium, *lustration for Rome, seldom so named (Serv. on Verg. Ecl. 3. 77; SHAAurel. 20. 3), usually linked with the *Ambarvalia's lustration of the fields (Festus Gloss. Lat. 112; Servius; SHA). Since it appears in no *calendar it may have been a movable festival (L. Delatte, Ant. Class. 1937, 114–17) or, based on the infrequent references, all late, it may have been a rarely performed lustration (cf. Ogilvie on Livy 1. 44. 2, and JRS 1961, 39) which anachronistically received its name by analogy with Ambarvalia. H. Usener placed it (Weihnachtsfest, 2nd edn. (1911), 1. 314–28) on 2 February as ultimately Christianized into Candlemas, unpersuasively despite Wissowa, RK 142 n. 12. Lucan (1. 592–638) describes an amburbium—but clearly an extraordinary ceremony.
