Astrology Symbols Meaning: Glyphs and Signs
Astrology Symbols Meaning: A Glyph Is a Whole Sentence
Astrology symbols meaning is really a question about shorthand. A birth chart is a crowded wheel, and no one wants to read the words "Venus in Aquarius in the seventh house, square to the Moon in Scorpio" written out fifty times, so astrologers use glyphs, small drawn marks that pack a whole word into a single sign. Each glyph has a history, usually a picture of what it stands for, and once you know the dozen or so marks that matter, a chart stops looking like a secret code and starts reading like a sentence. This page walks through the families one by one: the twelve signs, the ten planets, the aspects, and the smaller marks for angles and houses, and then puts them together in a real worked example so you can see how a string of glyphs becomes a reading.
The Twelve Sign Glyphs
The sign glyphs are the most used marks in astrology, and most of them are little pictures. Aries is drawn as a ram's horns, two curved strokes rising from a point. Taurus is a bull's head, a circle with two horns above it. Gemini is the twins, two vertical lines joined top and bottom, like a Roman numeral two. Cancer is the crab, two interlocking spirals that look like the number 69 turned sideways. Leo is the lion, a loop with a curling tail. Virgo is the maiden, a shape like the letter M with a loop crossing its last stroke. Libra is the scales, a horizontal line over a shape like an upside down bowl. Scorpio is the scorpion, an M shape with a stinging tail that ends in an arrow point. Sagittarius is the archer, a single arrow pointing up and to the right. Capricorn is the sea goat, a shape that starts like an N and ends in a curling fish tail. Aquarius is the water bearer, two wavy parallel lines. Pisces is the fish, two curved arcs facing away from each other, joined by a horizontal line.
Each sign also carries a season, an element, and a quality, and the glyph is only the doorway to those. Aries runs about March 21 to April 19 and is a fire sign. Taurus runs about April 20 to May 20 and is earth. Gemini runs about May 21 to June 20 and is air. Cancer runs about June 21 to July 22 and is water. Leo runs about July 23 to August 22 and is fire. Virgo runs about August 23 to September 22 and is earth. Libra runs about September 23 to October 22 and is air. Scorpio runs about October 23 to November 21 and is water. Sagittarius runs about November 22 to December 21 and is fire. Capricorn runs about December 22 to January 19 and is earth. Aquarius runs about January 20 to February 18 and is air. Pisces runs about February 19 to March 20 and is water. The dates are approximate, because the Sun enters each sign on a slightly different day each year, and the exact dates for any year are listed on the twelve zodiac signs page. When you see a sign glyph in a chart, read it as a style: the way a planet in that sign tends to express itself.
The Planet Glyphs
The planet glyphs are older than the sign glyphs in some cases, and several of them are built from three simple parts: a circle for spirit, a crescent for soul, and a cross for matter. The Sun is a circle with a dot in the center, spirit at the center of the self. The Moon is a crescent, the shape of feeling and change. Mercury is the most layered of the set, a circle topped by a crescent and crossed below, which astrologers read as spirit, soul, and matter joined, fitting for the planet of thought and messages. Venus is a circle over a cross, the mirror of the goddess, read as love and value rising above the material. Mars is a circle with an arrow rising from it, the shield and spear of the warrior, read as drive and assertion. Jupiter is a shape like the number 4, traditionally read as a crescent of soul over a cross of matter. Saturn is a cross over a crescent, like a scythe, read as structure, limit, and time. Uranus is a circle with an H shape beneath it, a mark that honors its discoverer William Herschel, who found the planet in 1781. Neptune is a trident, the sea god's three pronged spear. Pluto is a circle over a crescent over a cross, or in some charts the letters P and L joined for Percival Lowell, whose observatory found the dwarf planet in 1930.
Two of these glyphs cause most of the confusion for beginners, so they are worth fixing in memory now. Venus and Mars look like a pair because they are a pair: Venus is the circle above the cross, Mars is the circle below the arrow, and if you flip one you get something close to the other. The way to tell them apart is the top of the mark: a closed circle with a cross underneath is Venus, a circle with an arrow shooting out is Mars. The Moon's crescent is also easy to mix with the crescent inside Mercury or Jupiter, but the Moon stands alone, a single clean crescent with nothing attached. Learn the ten planet glyphs and you can read any chart's cast list at a glance.
The Aspect Glyphs
Aspects are the angles between planets, and their glyphs are small geometric marks placed between two planet glyphs on a chart. The conjunction, two planets at the same degree, is drawn as a small shape like a loop with a tail, or simply written as 0 degrees. The opposition, 180 degrees apart, is drawn as two rings linked by a straight stroke across the middle, which looks like the two planets facing each other across the wheel. The square, 90 degrees apart, is drawn as a small square. The trine, 120 degrees apart, is drawn as a triangle. The sextile, 60 degrees apart, is drawn as a six pointed star, two overlapping triangles, or sometimes as a simple asterisk-like mark. The quincunx, 150 degrees apart, has no single standard glyph and is usually written as the number 150 or the word inconjunct, which is its older name.
These marks matter because they change the sentence. Venus in Aquarius is one statement. Venus in Aquarius square the Moon in Scorpio is a different one, because the square glyph adds friction to the story. The triangle of a trine adds ease. The opposition's two circles add a pull between two poles. When you read a chart, the aspect glyphs are the verbs between the nouns: they say whether two planets cooperate, argue, or ignore each other. The opposition in astrology page works through one of these marks in full, and the same logic applies to the rest of the set.
Angles, Houses, and the Smaller Marks
Beyond signs, planets, and aspects, a chart carries a smaller set of marks for its structure. The Ascendant, the degree rising on the eastern horizon at birth, is written as ASC or Asc, and its glyph is an arrow rising from a horizontal line. The Midheaven, the highest point of the chart, is written as MC, from the Latin Medium Coeli, middle of the sky. Directly opposite it sits the Imum Coeli, written as IC, the bottom of the sky and the cusp of the fourth house. Opposite the Ascendant sits the Descendant, written as DSC, the degree setting on the western horizon. Together these four angles frame the wheel, and the houses of the chart fill the space between them.
A few more marks show up on most charts. The North Node is drawn as a shape like a horseshoe with a small circle, and the South Node is the same mark upside down; together they mark where the Moon's orbit crosses the ecliptic. A small letter R next to a planet means retrograde, the planet appearing to move backward from Earth's view. The degree sign, a small circle after a number, gives the planet's exact position inside its sign, such as 24 degrees of Pisces. Part of Fortune, a circle with a cross inside it, appears on some charts as an additional calculated point. None of these is decoration. Each one is a piece of information, and a chart reader who skips them is reading a sentence with words missing.
An Illustrative Example: Reading a Real Glyph String
This example is illustrative, not a real person's story. The best way to learn the glyphs is to read a real set of positions, so here is a chart cast for noon, universal time, on March 15, 1990, computed with the Swiss Ephemeris. The Sun stood at 24.64 degrees of Pisces. The Moon stood at 9.75 degrees of Scorpio. Mercury stood at 21.22 degrees of Pisces. Venus stood at 9.14 degrees of Aquarius. Mars stood at 2.84 degrees of Aquarius. Jupiter stood at 1.38 degrees of Cancer. Saturn stood at 23.34 degrees of Capricorn. Uranus stood at 9.22 degrees of Capricorn. Neptune stood at 14.29 degrees of Capricorn. Pluto stood at 17.62 degrees of Scorpio.
Read that as glyphs, and the story starts to form before any interpretation begins. The Sun's circle with a dot sits inside the two fish of Pisces, next to Mercury's layered mark in the same sign, so thought and identity share a watery, imaginative style. The Moon's crescent sits in Scorpio, 89.39 degrees from Venus in Aquarius, which is a square with an orb of only 0.61 degrees, a tight, exact angle. Venus and Mars both sit in Aquarius, the water bearer's two wavy lines, so affection and drive share an airy, independent style. Three slow planets, Saturn, Uranus, and Neptune, cluster in Capricorn, the sea goat, which is a generational signature of anyone born in that period. The glyphs alone, before a single interpretive word, already show the shape of the chart: a Pisces Sun with a Scorpio Moon, an Aquarius Venus and Mars, and a Capricorn stellium. That is what the symbols are for. They compress a page of positions into a picture you can hold in your head.
Confusions to Avoid and How to Practice
A few traps catch almost every beginner, and knowing them in advance saves a lot of misreading. The first is mixing up the sign glyphs that look alike: Aries and Taurus both have horns, but Aries is two curves with no circle and Taurus is a circle with horns on top. Leo and Virgo both curl, but Leo is a single loop with a tail and Virgo is an M shape with a crossed loop. The second is reading the aspect glyphs as planets: the triangle of a trine is not a sign, and the square of a square aspect is not a house. The third is treating the glyph as the whole meaning: the glyph for Saturn tells you which planet you are looking at, not what Saturn means in that chart, and the meaning comes from sign, house, and aspects together. The fourth is the retrograde R: it does not mean the planet is moving backward in space, only that it appears to from Earth, and it is a small mark with a large interpretive weight in many traditions.
The fastest practice is to take your own birth chart and label every glyph on it by hand, writing the name next to each mark until you no longer need the labels. Then learn how to read a birth chart step by step, and the glyphs will stop being symbols to decode and start being words you can read at sight. Start with what astrology is if you want the big picture first, and return to this page whenever a mark on a chart stops you. A glyph is a whole sentence, but only if you know the alphabet.

Frequently Asked Questions
What do astrology symbols mean?
Astrology symbols, or glyphs, are shorthand marks for the signs, planets, aspects, and chart angles. Each glyph packs a whole word into a single sign: the Sun is a circle with a dot, the Moon is a crescent, Aries is a ram's horns, and the trine is a triangle. Once you know the marks, a chart reads like a sentence instead of a code.
How many astrology symbols are there?
The core set is about thirty marks: twelve sign glyphs, ten planet glyphs for the Sun through Pluto, five major aspect glyphs for the conjunction, opposition, square, trine, and sextile, and four angle marks for the Ascendant, Descendant, Midheaven, and Imum Coeli. Extra marks such as the lunar nodes, the retrograde R, and Part of Fortune appear on many charts as well.
What is the difference between the Venus and Mars symbols?
Venus is a circle above a cross, the mirror of the goddess, and Mars is a circle with an arrow rising from it, the shield and spear of the warrior. They look like a pair because they are a pair, and the way to tell them apart is the top of the mark: a closed circle with a cross underneath is Venus, while a circle with an arrow shooting out is Mars.
What does the triangle symbol mean in astrology?
The triangle is the glyph for the trine, an aspect of 120 degrees between two planets. Astrologers read a trine as ease and flow between the two planets involved, in contrast to the square, drawn as a small square, which is read as friction and effort, and the opposition, drawn as two circles joined by a line, which is read as a pull between two poles.
How do I learn to read astrology symbols on a chart?
Learn the families one at a time, signs first, then planets, then aspects, and practice by labeling every glyph on your own birth chart by hand until you no longer need the labels. The worked example on this page uses real positions computed with the Swiss Ephemeris for noon on March 15, 1990, and shows how a string of glyphs becomes a readable picture of a chart.
