What name conventionally appears between Wolfgang and Mozart in the composer's widely used full name?

Amadeus

Although baptized as Joannes Chrysostomus Wolfgangus Theophilus, the composer often used the French version 'Amadè' during his lifetime. The name 'Amadeus' is the Latin translation of the Greek 'Theophilus,' both of which mean 'lover of God.' It became his standard middle name in popular culture largely due to 19th-century biographies and the famous 1984 film.
