Scorpios

[ReneZ]

The text opens with "ophiucus" (Ophiuchus) aka serpentarius and does not mention Scorpius / scorpion in the first line, this will come from the original Latin text version, maybe the scorpion was intertwined with the snakeholder figure to link him with the "modern" understanding of that zodiac,

In the night sky, the constellations of the snake (Serpens) and the snake holder (Ophiuchus) are directly above the constellation Scorpius.
