('crematorium'). An architectural cremation place for Roman rulers, of which often only an altar remains. The best-known example is the Ustrinum of Augustus on the Field of Mars in Rome (Campus Martius; Roma III.) near the Mausoleum Augusti; Strabo (5,3,8), describes it as lavishly built and preserved, after the act of cremation, as a monument. Remains of other ustrina on the Field of Mars are assigned to the emperors Hadrianus, Marcus Aurelius and Antoninus Pius.
