Among the scarce references to ancient astrology in Plutarch’s works, we must pay attention
to questions of astrometeorology. Such references, limited to the Sun and the Moon, concern
popular beliefs on the influence of both stars on plants and animals. In this paper I analyse
some passages from the Quaestiones convivales where Plutarch echoes those beliefs concerning
the effects of the Moon and the Sun on the nature and physiology of the beings of this world.
Similar astrometeorological prescriptions are also found in astrological texts, such as lunaria
from late antiquity and the Middle Ages.
