Terms and Bounds
Terms and Bounds explains unequal degree ranges and their table-dependent rulers. 17° Aries lies in Mercury’s 14°–21° bound under that table.
Overview
Terms or bounds divide each sign into unequal degree ranges ruled by traditional planets, with Egyptian, Ptolemaic, and other tables producing different rulers. The page separates calculation from interpretation and keeps this worked result conditional: 17° Aries lies in Mercury’s 14°–21° bound under that table. Verification follows this declared method: For a planet at 27° Capricorn, specify the table, use full-precision longitude at the boundary, and return the range start, end, and ruler.

Definition and exact scope
terms or bounds divide each sign into unequal degree ranges ruled by traditional planets, with Egyptian, Ptolemaic, and other tables producing different rulers
Calculation or decision rule
for a planet at 27° Capricorn, specify the table, use full-precision longitude at the boundary, and return the range start, end, and ruler
Worked case and illustrative near miss
17°♈; Egyptian bounds selected; Aries intervals read in degree order. 17° Aries lies in Mercury’s 14°–21° bound under that table.
Illustrative near miss: Using a Ptolemaic bound result while labeling the receipt Egyptian, or treating each bound as an equal 6° slice.
School and variant boundary
Tables and procedures differ by author, era, translation, and sect; the selected authority must remain visible.
Product, safety, and verification boundary
OpenFate presents Terms and Bounds as a sourced knowledge method and does not claim a dedicated calculator or generated reading for it. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Terms and Bounds cannot diagnose a person, remove consent, or guarantee an event.
