Attitudes to gladiator "munera" varied; they were very popular, and thus politically useful. But they were also thought luxurious, self-indulgent and contrary to Roman morality – Publius Sempronius Sophus divorced his wife because she had attended a "munus" without his knowledge. Sulla showed his usual political acumen during his stint as praetor, when he broke his own sumptuary laws to honour his dead wife, Metella, with an exceptionally lavish gladiator "munus". The host ("editor") of a "munus" stood to gain votes in his political career, for even a promise of funeral games. The gladiators themselves could be admired for their courage, and despised for the bloodiness of their profession, which sometimes approximated that of excecutioner. The insulting term "bustuarius" ("tomb-man") was sometimes used for the lower class of gladiator, who might thus be perceived as provider of fodder for the spirits of the dead. Julius Caesar broke any strict link between funerals and "munera" when he dedicated his "ludi" of 65 BC, with its 320 pairs of gladiators, to his father, who had been dead for 20 years.
