At count 1:41 there is a note in the french horns that I hear even in a couple famous recordings that isn't right. It's corrected in Karajan and Serafin's recordings but many conductors don't catch it as bizarre as it sounds, but it is a mistake in the Ricordi score. That measure should start on concert A flat in the horn and resolve up to the B flat printed. You can hear where it is easily by trying to sing the soprano part on the text "Il labbro suo vedea"

Va muuuuuy rápido!
This base is too fast, impossible to sing decently!
