The book is named for seven days. Its weekday sequence brings a larger set of names, times, and ritual objects into a memorable printed order.

A weekly table, not a universal seal set
The Heptameron’s printed arrangement proceeds through considerations for Sunday to Saturday. In Peterson’s edition the weekday chapters follow preliminary material about circles, garments, names, prayers, and the manner of working. The day chapters gather planetary and angelic associations so that one weekday can be read as a unit. A separate table handles angels of the hours. This is a layout choice in a particular textual tradition; it should not be mistaken for a timeless list on which all Solomonic books agree.
Names are especially sensitive to copying and translation. Latin manuscripts, early prints, and Robert Turner’s English version do not all transmit every letter alike. Peterson’s comparison of angel names across several witnesses shows why a standalone online image labelled “the seven authentic Heptameron seals” lacks enough evidence. The lines of a seal may belong to a particular edition, manuscript, or later redrawing. Their differences reflect copying and translation rather than a single unchanging series.
How the circle changes with time
The opening circle section says the circle’s form is adjusted for the time of year, day, hour, spirits, and associated celestial region. Its written names include an hour angel, a day angel, seasonal terms, and other names. The premise is therefore variable: the printed description is not a single static emblem that can be copied without context. The circle’s nested bands and directional names are part of a historical theory of ordered space and time.
It is useful to read the words “circle” and “seal” separately. The circle is a spatial arrangement described in the text; a seal is a sign linked with a particular angel. Diagrams in a scanned witness might reflect engraver or compositor choices as well as the textual instruction. The 1559 Bavarian State Library object offers a way to inspect an early printed form. Peterson’s modern digital edition adds comparison notes, which are commentary rather than evidence that every manuscript has the same graphic arrangement.
Worked comparison: west-wind Monday and east-wind Tuesday
Set Monday beside Tuesday and the weekday chapter becomes easier to read. Each day follows the same chain: the day and its planetary government, named angels and their seal, a king of the air with ministers, a wind and directional angels, then a conjuration and a statement of attributed effects. Monday groups Gabriel, the air king Arcan, and the west wind within a lunar day; Tuesday shifts to Samael, the king Samax, and the east wind within a martial day. The repeated field order turns a long list into a timed ritual record. The wind is one coordinate in that record, not an independent weather charm detached from the day, names, and framing prayers.
The comparison also exposes what transmission changes and what it preserves. Turner prints the Monday minister as Abuzaha where the aligned early Latin has Abuzaba; on Sunday his Huratapal corresponds to Huratapel in another printed form. Those small changes do not replace the weekday architecture: Monday still points west and Tuesday east, and each keeps its own ruler, ministers, seal, and claimed purposes. A reader can therefore separate two kinds of evidence. The stable sequence shows how the compiler organized an operation, while a shifted letter shows why a name or seal copied from one witness should not silently stand for every version of the Heptameron.
