This article presents a new hypothesis about the urban arrangement and function of the southeast end of the Forum of Caesar, together with the Forum of Augustus, the Curia Julia and the present-day church of SS. Luca e Martina, when the area was finalized in 2 BCE. The analysis focuses on the geometric framework of the extant structures and the topography of the site and, in relation to them, a new interpretation of the historical records and the archaeological data. It demonstrates that Augustus and his architects authored the urban composition and architectural forms of the entire area, including making significant changes to the original design of the Forum of Caesar. The article also shows that the site of the church of SS. Luca e Martina was the location of the Augustan Chalcidicum, which served as the monumental entrance to the first two Imperial fora.

This paper attempts to put the Gorgon from the pediment of the Temple of Sulis Minerva at Bath into a wider provincial context, by arguing for links between the Gorgon and first- and early second-century imitations in Gaul and Spain of the iconography of the Forum of Augustus in Rome. These imitations, part of what might be called a ‘visual language of empire’, served to connect the urban spaces of the provinces to Rome; by linking the Gorgon to this trend and setting aside interpretations of the Gorgon which have focused on his perceived status as a ‘Romano-Celtic’ masterpiece, we can justify more satisfactorily his position as the centrepiece of a pediment dominated by imperial imagery.

This paper makes two arguments. The first is that Trajan deliberately orchestrated the dedication of his Column on 12 May, the anniversary of the dedication of the Temple of Mars Ultor, to coincide with the beginning of a new war against Parthia in a.d. 113. The second is that although most modern commentators focus on the function of Mars Ultor as avenger of Caesar, the evidence of his actual invocation from the late first century b.c. through the third century a.d. more strongly supports another interpretation: as agent of vengeance against foreign enemies, and against Parthia/Persia in particular.
