Abstract

Part of the baths regulations preserved on a bronze plaque, engraved more or less identically on each side, from the copper mine at Vipasca, Lusitania. The manager is to wash, clean and grease the waterheating vats once a month. Such vats, as mentioned by Vitruvius in his discussion of public baths , were three in number: aena supra hypocausim tria sunt componenda. They were sizeable articles: Propertius seems to see himself tortured in one: Veneris torrebar aeno. The greasing was to keep aerugo, copper rust, at bay; for this purpose Cato in general recommends amurca, lees of olive oil: ahena omnia amurca unguito…et aerugo non erit molesta; and also for greasing axles amurca axem unguito. For bronze tablets exposed to the weather such as the numerous public records on temple walls and the like Pliny recommends olive oil: aera…robiginem celerius trahunt…nisi oleo perunguantur. The phrase e recenti which occurs in both versions of the text is unexampled, and the CIL editors suggest that it means ex integro, afresh. However I am inclined to think that the engraver had a faulty copy in front of him and we should read adipe recenti
