Fra Angelico, The Crucifixion: Detail, Jacob the Patriarch
Convent of San Marco, Florence
This detail is from the border around the main image of the Crucifixion. The banderole reads ad [p]redam descendisti fili mi dormiens accubuisti ut leo, "to the prey, my son, thou art gone up: resting thou hast couched as a lion." These are Jacob's words to Judah at Genesis 49:9. Comments on this passage collected in the Glossa Ordinaria (I, 451-52) are rather confused but generally assume that as "son" Judah is a type of Christ whose "resting" refers to his time in the tomb before his resurrection.
