Image Name First described Equation Comment
circle The trivial spiral
Archimedean spiral (also arithmetic spiral) c. 320 BC
Fermat's spiral (also parabolic spiral) 1636[1]
Euler spiral (also Cornu spiral or polynomial spiral) 1696[2] using Fresnel integrals[3]
hyperbolic spiral (also reciprocal spiral) 1704
lituus 1722
logarithmic spiral (also known as equiangular spiral) 1638[4] Approximations of this are found in nature
Fibonacci spiral circular arcs connecting the opposite corners of squares in the Fibonacci tiling approximation of the golden spiral
golden spiral special case of the logarithmic spiral
Spiral of Theodorus (also known as Pythagorean spiral) c. 500 BC contiguous right triangles composed of one leg with unit length and the other leg being the hypotenuse of the prior triangle approximates the Archimedean spiral
involute 1673

involutes of a circle appear like Archimedean spirals
helix a 3-dimensional spiral
Rhumb line (also loxodrome) type of spiral drawn on a sphere
Cotes's spiral 1722 Solution to the two-body problem for an inverse-cube central force
Poinsot's spirals
Nielsen's spiral 1993[5]
A variation of Euler spiral, using sine integral and cosine integrals
Polygonal spiral special case approximation of logarithmic spiral
Fraser's Spiral 1908 Optical illusion based on spirals
Conchospiral three-dimensional spiral on the surface of a cone.
Calkin–Wilf spiral
Ulam spiral (also prime spiral) 1963
Sack's spiral 1994 variant of Ulam spiral and Archimedean spiral.
Seiffert's spiral 2000[6] spiral curve on the surface of a sphere

using the Jacobi elliptic functions[7]

Tractrix spiral 1704[8]
Pappus spiral 1779 3D conical spiral studied by Pappus and Pascal[9]
doppler spiral 2D projection of Pappus spiral[10]
Atzema spiral The curve that has a catacaustic forming a circle. Approximates the Archimedean spiral.[11]
Atomic spiral 2002 This spiral has two asymptotes; one is the circle of radius 1 and the other is the line [12]
Galactic spiral 2019 The differential spiral equations were developed to simulate the spiral arms of disc galaxies, have 4 solutions with three different cases:, the spiral patterns are decided by the behavior of the parameter . For , spiral-ring pattern; regular spiral; loose spiral. R is the distance of spiral starting point (0, R) to the center. The calculated x and y have to be rotated backward by () for plotting.[13]
