Astrology pattern draws on the graphic language astrology uses to represent relationships between celestial bodies: symbolic glyphs for planetary "aspects" (angles between planets in a horoscope), the twelve zodiac signs grouped into four elemental sets, and - notably for surface pattern - the fact that many of these aspect angles correspond directly to regular star polygons (pentagram, heptagram, octagram, decagram, dodecagram, and more). The source is an astrology reference on aspect theory rather than a design source, so this page focuses on the visual/symbolic vocabulary it documents.

The source's natal chart illustration shows aspects marked with distinct symbols and colours (for example, red for a square aspect, green for a trine), giving astrology imagery a built-in convention of colour-coded geometric glyphs radiating from a central point or wheel. Several aspects are explicitly tied to named regular star polygons: the quincunx to a dodecagram {12/5}, the septile family to heptagrams {7/2} and {7/3}, the octile family to an octagram {8/3}, the novile family to enneagrams {9/2} and {9/4}, the decile family to a decagram {10/3}, the undecile family to hendecagrams, and the semioctile family to hexadecagrams - giving this motif category a rich set of ready-made star-polygon forms.

The source's visual system is organised as a circular chart (a "wheel" of 360°) with planets and aspect lines plotted around the circumference - structurally a radial/mandala-type composition rather than a grid or drop repeat. Regular polygon and star-polygon forms (triangle, square, hexagon, pentagon, pentagram, heptagram, octagram, decagram, dodecagram, hendecagram, hexadecagram) are named directly as the geometric shapes corresponding to specific aspect angles.

• Zodiac signs and their symbols/glyphs (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces)
• Aspect glyphs: conjunction, opposition, square, trine, sextile, semisextile, quincunx, and further minor-aspect symbols
• Star polygons associated with aspect geometry: pentagram, heptagram, octagram, decagram, dodecagram, hendecagram, hexadecagram, enneagram
• The four elemental groupings of the zodiac: Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), Water (Cancer, Scorpio, Pisces)
• The natal chart/horoscope wheel as a compositional device

The source notes colour-coding of aspect types on natal charts (e.g. red for a square, green for a trine) as a functional convention for distinguishing "hard" from "easy" aspects, rather than a decorative palette. No broader stylistic conventions (line weight, rendering style) are described.

The source traces the technical history of aspect theory rather than the decorative history of astrological imagery: the major aspects (conjunction, sextile, square, trine, opposition) are termed "Ptolemaic Aspects" after Ptolemy's 1st-century AD definitions; Johannes Kepler expanded the aspect system in his 1619 book Harmonice Mundi; and John Addey later developed the modern harmonics-based approach. Historical interest in planetary conjunctions (particularly Jupiter-Saturn "great conjunctions") as omens is documented from medieval Arabic astrology through the Renaissance, referenced in period writings by Roger Bacon, Dante, and Shakespeare, declining sharply after 1603.

Not documented in the source. The reference material is a technical astrology article on aspect calculation and contains no textile, fashion, stationery, or other surface pattern application information; any claim about zodiac or celestial motifs in current surface pattern markets would be speculative and is omitted.
