The first on the list, Santa Maria Sopra Minerva, in on my "don't miss" list. The narrator speaks to the bronze drapery around the Risen Christ's privates but fails to mention it's true purpose. A monk vandalized the statue with a hammer because Jesus' immodesty offended him, so that's what they're hiding. Besides an emascualted Jesus, there's a Bernini obelisk in the parking lot. And Sopra Minerva was where Galileo, who was suffering from imprisonment, the infirmities of old age, and the hospitality of an Inquisition, recanted his theory of heliocentricity.
RE: Moses in San Pietro in Vincoli, another case of a mistranslation by St Jerome (horns on Moses' head instead of rays of light). He also mistranslated Exodus 20:13 from the Pentateuch, substituting the Latin for "kill" (occides) for the Hebrew "murder" (tirtzach). His Latin Vulgate bible was the basis for many English translations, including the KJV, which perpetuated his 'alteration,' which has become foundational to no end of pacifist movements. But according to the Hebrews (who are the only ones who have any legitimate say in this matter), G-d did not write the word "kill" (or its Hebrew equivalent) on either of the tablets Moses brought down from the mountain.
And Jerome apparently thought he was making a clever pun when he used the Latin "malum" rather than a more straightforward literal translation of the generic "fruit" used in the Hebrew, referring to the fruit of the Tree of Knowledge in the Garden of Eden. "Malum" can refer to any fleshy, seed-bearing fruit -- such as an apple -- but it also is Latin for 'evil.' So perhaps he was being a bit cheeky with this double entendre. And starting with Dürer's 1504 engraving, "Adam and Eve," which depicted the Tree of Knowledge as an apple tree, the apple has been canon.
In his panels of the fall of man in the ceiling of the Sistine, Michaleangelo chose a fig tree, presumably because he was familiar with the Hebrew and wasn't impressed with the "apple" interpretation, and he knew that Adam and Eve had clothed themselves in fig leaves once they saw that they were naked, and the Hebrew does mention fig trees in the Garden.
The narrator states that San Pietro is five minutes from the Collosseum, but that's five minutes by taxi ... up a pretty steep hill.
I hate the layout of David in he Academia. You first sight Michelangelo's David from about 30 yards away, down a long gallery. So the statue's enormity (17 feet tall!) isn't apparent until you've walked some distance to get to it, which mutes it impact. I encourage companions to stare at the floor until we are at his feet, so their first glimpse is nearer to the perspective that Michelangelo had in mind when he carved it (in one case I used my fedora to shield the eyes of my companion so as to preserve the surprise). It was intended to be placed high off the ground atop one of the Duomo's pilasters.
A replica where Michelangelo probably intended it to go:
If memory serves, this is about 75 feet above ground level. Which explains why his willy is so ... modest. If Michelangelo had made it 'normal-sized' from eye-level, it would have looked gargantuan from a street level perspective.
