I like neoclassical stuff too. He's a southerner but I dig Titian's stuff. His Venus of Urbino is one of my favorite paintings (and I hate Manet's profane Olympia).
The problem and benefit of these sorts of works is that the narrative is so allusive and involved that I often find it inaccessible without a history/mythology lesson. I'm guessing the first pic you posted has to do with the dude who founded the Jesuits but beyond that I'm lost as to who is who and what they're up to.
The second looks to be an adoration (I'm a little adorationed & annunciationed out), but I'm never able to appreciate the difference between one adoration and another in terms of narrative oriented non-technical aspects. Storywise, you seen one adoration you've seen 'em all. I prefer the mythological stories to the Christian ones even though I usually need it explained to me.
The narrative of Christian themed paintings is now not so relevant. The masterpieces from the Renaissance have now gained significance above the cultural codes of their time.
I had pretty much the same feeling as you when I went for a 3 week vacation in Tuscany (went to Lucca, Volterra, Prato, Pistoia, Cortona, Arezzo, Siena, San Gimignano, etc.....). I must have seen more than a thousand Madonnas. I first got quickly tired of it but then slowly I started seeing how painters like Simone Martini, Lorenzo Monaco, Filippo Lippi, Duccio, etc.....managed to use a pre formatted form to express things way above the religious symbol.
