AEIOU is known as the Vowel Song,
not to be confused by the Colors of the Rainbow Song.
A.E.I.O.U., was a symbolic device personally used by the Habsburg emperor Frederick III (1415–93), who had a fondness for mythical formulae. He habitually signed buildings such as Burg Wiener Neustadt or Graz Cathedral as well as his tableware and other objects with the acronym.
A.E.I.O.U. is the motto of the Theresian Military Academy established in 1751.
