In western astrology the zodiac contains 12 signs each of which is assigned one of 4 elements (fire, earth, air, or water) and one of 3 modalities (also known as qualities) (fixed, cardinal, or mutable). There are 12 possible combinations of element and modality and each of them is uniquely assigned to a sign: for example, Taurus is fixed earth, and Sagittarius is mutable fire.
In Hindu astrology the assignment is similar, except that the three qualities are fixed, movable, and dual, corresponding respectively to western astrology's fixed, cardinal and mutable: thus for example Sagittarius is dual fire.
Graphical symbols have been assigned to each of the signs and I am also aware of symbols for the four elements. Meanwhile there are symbols in astrology for planets and for aspects.
What symbols have been used, if any, for the modalities (qualities)?
