Dividing the sun's path into twelve
The twelve zodiac signs treat the ecliptic as twelve divisions. They were also taken into Buddhist sukuyō texts, where names corresponding to the twelve signs of the zodiac known from Western astrology appear in different kanji. The forms shown here are images that represent stars and divisions as deities.

Reading them as part of the history of sukuyō
Shōhōin notes that the twelve zodiac signs appear in texts such as the Sukuyō Kyō and the 七曜禳災訣. They belong to a history in which astronomy and religion met: reading the positions of the stars, making calendars and performing prayers to remove misfortune.
