Libro de Astromagia, folio 21r

The picture shows folio 21r containing a circular miniature with Luna in the centre. The folio closes the part of the text beginning with folio 18v having a similar large miniature.

The circular miniature (a diagram) is divided into 28 segments for the lunar mansions. The outer ring contains talismans.

Luna, a planetary deity, embodies the divine essence of the Moon. In classical mythology and Renaissance art, Luna is depicted riding a celestial two-horse chariot known as a biga, symbolizing her nightly journey across the sky as the female counterpart to the sun god, Sol, driving a four-horse chariot (a quadriga) during the day.

However, in this miniature, Luna is represented as a woman riding a rabbit. In medieval iconography, the association between the Moon and the rabbit stems from fertility, speed, and the lunar cycle. Because a hare's gestation period was poorly understood, it became the ultimate symbol for the waxing and waning Moon, which was thought to control bodily fluids, growth, and multiplication.
