Like Plutarch, Apuleius seems to take for granted the existence of daemons. They populate the air and seem to, in fact, be formed of air. They experience emotions just like human beings, and despite this their minds are rational. In light of Apuleuis’ experience it is worth noting that when magic is mentioned in Roman laws, it is always discussed in a negative context. A consensus was established quite early in Roman history for the banning of anything viewed as harmful acts of magic. The laws of the Twelve Tables (451–450 BCE) for example expressly forbid anyone from enticing his neighbors’ crops into his fields by magic. An actual trial for alleged violation of these laws was held before Spurius Albinus in 157 BCE. It is also recorded that Cornelius Hispanus expelled the Chaldean astrologers from Rome in 139 BCE ostensibly on the grounds that they were magicians.
