The '''Tetractys''' ([[greek language|greek]] Τετρακτύς) is a [[triangular number|triangular figure]] consisting of ten points arranged in four rows: one, two, three, and four points in each row. As a [[mysticism|mystical]] symbol, it was very important to the secret worship of the [[Pythagoreans]].

*The Tetractys symbolized the [[classical element|four elements]] — [[earth]], [[air]], [[fire]], and [[water]].
*The first four numbers also symbolized the [[Harmony of the Spheres|harmony of the spheres]] and the [[Cosmos]].{{Fact|date=February 2007}}
*The four rows added up to [[10 (number)|ten]], which was unity of a higher order (in [[decimal]]).
*The Tetractys represented the organization of [[space]]:
**the first row represented zero-[[dimension]]s (a [[Point (geometry)|point]])
**the second row represented one-dimension (a [[Line (geometry)|line]] of two points)
**the third row represented [[Cartesian plane#Two-dimensional coordinate system|two-dimensions]] (a [[plane (geometry)|plane]] defined by a [[triangle]] of three points)
**the fourth row represented [[three-dimensional space|three-dimensions]] (a [[tetrahedron]] defined by four points)
A [[prayer]] of the Pythagoreans shows the importance of the Tetractys (sometimes called the "Mystic Tetrad"), as the prayer was addressed to it.
:''"Bless us, divine number, thou who generated gods and men! O holy, holy Tetractys, thou that containest the root and source of the eternally flowing creation! For the divine number begins with the profound, pure unity until it comes to the holy four; then it begets the mother of all, the all-comprising, all-bounding, the first-born, the never-swerving, the never-tiring holy ten, the keyholder of all"''.
