Traditional naming patterns are used for both stallions and mares, required by Lipizzan breed registries. Stallions traditionally are given two names, with the first being the line of the sire and the second being the name of the dam. For example, "Maestoso Austria" is a horse sired by Maestoso Trompeta out of a mare named Austria. The horse's sire line traces to the foundation sire Maestoso. The names of mares are chosen to be "complementary to the traditional Lipizzan line names" and are required to end in the letter "a".
