amburbium
- the expiatory procession round the city of Rome, at which sacrifices were offered (v. the preced.); Serv. ad Verg. E. 3, 77; Paul. ex Fest. p. 17 Müll.: lustrata urbs, cantata carmina, amburbium celebratum, ambarvalia promissa, Vop. Aur. 20 (described in Luc. 1, 592 sq.).
AMBU´RBIUMor AMBURBIA´LE, a sacrifice which was performed at Rome for the purification of the city, in the same manner as the ambarvalia was intended for the purification of the country. The victims were carried through the whole town, and the sacrifice was usually performed when any danger was apprehended in consequence of the appearance of prodigies, or other circumstances. (Obseq. de Prodig. 100.43; Apul. Met. iii. ab init.; Lucan (Luc. 1.592seq., where it is described). Scaliger supposed that the amburbium and ambarvalia were the same; but their difference is expressly asserted by Servius (ad Verg. Ecl. 3.77) and Vopiscus (amburbium celebratum, ambarvalia promissa, Aurel. 100.20; cf. Preller, Röm. Myth. p. 372; Marquardt, 6. p. 195). [AMBARVALIA]
