Let's keep looking at the outside of the Baptistry:

Ghiberti, in the mid-Early Renaissance: He worked on this second set of doors for the Baptistry from 1425-1452:

Like his colleagues, such as Donatello, he is now more realistically oriented as we see society becoming more humanistic. Here his low relief backgrounds demonstrate the new understanding of perspective, really succeeding at creating three dimensional space on a flat surface. The figures themselves are high relief. And oh, what high relief! No deeper than three inches but they appear to be freestanding. Check out some of the scenes below. All of the panels here are scenes from the Old Testament:

Ghiberti's Second set of doors on the Baptistry:

Let's look closer:

Story of Joseph:

You can see Moses on the mountaintop here.

Here, David slays Goliath:

Ah that Renaissance individualism:

Ghiberti, on the left, and his son.

The story of Issac. See Issac blessing Jacob in the right corner.

From left to right: From the birth of Adam and Eve to the fall in the garden. See the original below.

The original panels in the Duomo museum. Their new home is being finished, here.

The original panel of the birth of Adam and Eve,etc. Follow from left to right: Adam is born, Eve then, out of a rib of Adam and then we see Eve's distress after they have committed deliberate original sin.
