breakfast at brera

i'm not exactly a fan of christian iconography, so medieval art was something really hard to me to enjoy. but this was just one more case of prejudice about something ignored, and now i'm at peace with ten centuries of art history thanks to my profusion of leisure time (but i should confess that lady marchmain can still not be proud of my religious views). after spending hours feeling that the end would never come of this enormous collection of medieval art owned by the pinacoteca di brera in milano, i have found some details of these paintings, i would like to bring it up

is it a gay couple behind baby jesus? 
-giovanni bellini - madonna col bambino-

this is a huge painting and behind the main scene it is happening so many more interesting things, like a dog barking at a dromedary, which refuses itself to move (?)   
-gentile and giovanni bellini - la predica di s. marco in una piazza di alessandria-

pretty doggy I 
-giovanni mansueti - s. marco battezza aniano-

pretty doggy II 
-veronese - ultima cena-

pretty doggies killing a cat 
-veronese - cena in casa di simone-

pretty doggy III (well, i don't have my dogs with me, right?! and i like dogs!!!!)
-bonifacio veronese - mosè consegnato alla figlia del faraone-

how is this guy still alive? if i were alive with a dagger on my chest, i would probably be doing something more interesting than praying... 
-carlo crivelli - trittico di san domenico-
