Saltire

A saltire, or Saint Andrew's Cross, is a heraldic symbol in the form of a diagonal cross ☓ or letter x. Saint Andrew is said to have been martyred on such a cross. In the Russian Orthodox tradition, the phrase Saint Andrew's Cross is often equated with the Orthodox cross, because of the tradition that Saint Andrew used such a cross when preaching in the respective regions. The Saltire design is however distinct from that of the Orthodox Cross.

It appears in numerous flags, including those of Scotland and Jamaica, and other coats of arms and seals. A variant, also appearing on many past and present flags and symbols, is the Cross of Burgundy flag.

A warning sign in the shape of a saltire is also used to indicate the point at which a railway line intersects a road at a level crossing.

In Unicode, the cross is encoded at U+2613 ☓ saltire (HTML: ☓) and U+0078 x latin small letter x (HTML: x).
