In this mysterious bilingual astrological madrigal 'the ancient god Biber' is probably Iopiter (Latin for Jupiter {Zeus}, the god of the sky in Roman mythology). The 'seven stars' may refer to Ursa Major/Minor and the myth where Zeus's jealous wife Hera (Juno to the Romans) transforms Callisto into a Great Bear, when Zeus, then to protect her, places her (constellation) in the sky, becoming immortal. 'Trine" (120°) and 'Sextile" (60°) are the aspects of two zodiac planets distance from each other. The 'fixed poles' may be the earth's axis (North/South Pole).
