The Roman villa at Cercadilla, a huge complex dated from the very beginning of IVth century, has just been the object of a highly valuable publication by R. Hidalgo. This provides new evidence for Cordoba's prosperity, which city Diocletian promoted to capital of Baetica, to be later superseded in that function by Hispalis under Constantius II. However one must disagree on one point with the editor, i.e. on his interpretation of the building as Maximianus Herculius's palatium during his military operations in Hispania and later in Africa, which would constitute the first known instance of a Tetrarchic palace, prior to Trier. Against such an attribution, Author argues that occidental aristocratic villas were in no respect inferior to the imperial residences, as shown among others by Olympiodoros of Thebes' well known text and confirmed by archaeological remains (cf. Piazza Armerina, Chiragan, etc., but equally many oriental instances). Conversely, imperial travels did not usually bring about palatial buildings. As regards Maximian, the circumstances and aims of his way through Spain rule out choosing Cordoba as his operational basis. As an alternative explanation, given Cercadilla's proximity to the city (600m from the walls), the author suggests including this monument in the list of known governor's residences (praetoria).
