The fourth heaven of Sefer HaRazim is dominated by a single spectacular image—the chariot of the sun, pulled across the sky each day by angels of fire. This is not a metaphor. The text describes the sun's journey as a literal procession, managed by angelic charioteers who guide the solar orb from its rising in the east to its setting in the west.
The chariot of the sun is driven by the angel Shamshiel (שמשיאל), whose name means "Sun of God." Shamshiel rides in a chariot of flame, flanked by two rows of angels—one on each side—who steadily beat their wings to generate the solar wind that drives the chariot forward. Behind the chariot trail the ministering angels who collect the leftover sparks of light and recycle them for the following day's sunrise.
This solar mythology has deep biblical roots. (Psalms 19:5-7) describes the sun as emerging "like a bridegroom from his chamber" and running its course across the heavens "like a strong man rejoicing to run his race." The Talmud (Pesachim 94b) debates whether the sun travels above the firmament at night or below the earth. Sefer HaRazim adopts the latter view—the sun passes through a subterranean tunnel at night, guided by angels through the darkness until it emerges again at dawn.
The fourth heaven also contains the angels who govern the moon and stars. The lunar angels follow a separate chariot, smaller and dimmer, which tracks the moon through its monthly phases. The star-angels are fixed in their positions, each one holding a torch of light that appears from earth as a single point of brightness in the night sky.
The practical adjurations of the fourth heaven deal with influence and authority. Those who invoke the sun-angels are promised success in leadership, the ability to command respect, and favor in the eyes of rulers. The sun, after all, is the king of the heavenly bodies—and its angels confer a measure of its royal authority on those who call upon them properly.
