Abstract
In their recent article on this subject, Rose and Sullivan suggest that we read: super scorpionem locustam, super sagittarium oculatam, super capricornum caprum et cornutam, etc. This is attractive and can, I suggest, be supported by a further argument.I propose that locustam be regarded as a pun on the celebrated lady poisoner of the period, Locusta. According to Tacitus, she was already infamous by the year 54, and continued to be a valuable tool of Nero throughout his reign. Petronius is fond of puns, and the passage under discussion contains more than one. And the suggested play on locusta may be confirmed by Trimalchio himself, a little later on, in his lecturette on astrology: in scorpione venenarii et percussores.
