Aquarius vs Aries: the two signs side by side
Aquarius is air and fixed, ruled by Uranus. Aries is fire and cardinal, ruled by Mars. Different elements means they take the world in differently, which is where both the interest and the friction live. Different modalities means they move at different speeds — one starts, the other holds or adapts.
