The Holy Apostles
I had studied the facial features of the apostles, so I’ll try to identify them here, as they are well detailed.
In the bottom row, Peter (gray hair, square beard) and Paul (bald, dark hair, nervous look) are in the center. Matthew is next to Peter, and James the Less (the Just, bishop of Jerusalem and Brother of the Lord) is next to Paul. All four have distinctive features that leave no doubt.
The next row from left, we see Philip and Bartholomew. Philip is easy to confuse with John as both are young, and John is shown on the right of the second row. How do I know that it is not John on the left? Because the man with a long face, straight moustache and a crop of unruly hair is decidedly Bartohlomew his friend, while the man next to John, i.e. second from right is decidedly older, gray-haired and bushy-bearded Simon the Zealot. Andrew, — pointy beard, a lot of hair and close-sitting eyes is in the center of that row.
In the top row we have James the greater brother of John, the Boanergos, Thomas the incredulous Didymos, and Jude. Here I am not 100% sure, except James is shown looking fondly at, and resembling John, and Jude is usually shown dark haired with a big beard. Besides, Thomas seems to have a tortured face.
The fact that Andrew is holding a scroll and John is not, is a bit confusing, as the others holding books and scrolls are those who left scripture. However, there can be no doubt that it is Andrew, — a very distinctive face.
