Bass and Contralto duets

[Elvira_R0825]

I'm looking for bass & contralto duets. I know for sure there are some.
Preferably love duets, but not necessarlily. There are basses wooing contraltos, such as Achilla in Handel's Julio Cesare (or Polifemo wooing Galatea in Aci, Galatea e Polifemo). But they hardly get to sing together. I can just remeber one of Mustafa and Isabella in L'Italiana in Algeri. The only bass & contralto love duet that I can remember is one of Sir Marmaduke and Lady Sangazure from Sullivan's Sorcerer ("welcome, joy").
The only condition is that a contralto should be playing a female character (i.e. not a trouser role).
Recitatives are also fine, not only arias.
Any style/period is ok.
Not necessarlily love duet, could be anything.
And in case it's hard to find bass & contralto duets, let's also include bass-baritone and mezzo duets.
Thanks.
