It's likely my flawed memory of French, but I thought Acte referred to the Acts?

I'm trying to think of what word actually refers to the No. 1 or the
No. 7 in these...

* Oratorio in F major, K. 74c/118 "La Betulia liberata": III. Parte
prima: No. 1 Aria "D'ogni colpa la colpa maggiore" (Ozia)

* Mitridate, rè di Ponto, K. 74a/87: Act I, Scene X. No. 7 Marcia. Maestoso

Off topic, but does anyone know of any example work which does indeed
have two common names?
