Three days ago I pointed out in the Panel of the Archbishop some of the ‘plagues’ associated with the biblical plagues inflicted on the Egyptians. Besides the plagues of (1) frogs; (2) gnats; (3) boils; and (4) death of the firstborn, there are others:
The thunderstorm of hail and fire (5) is matched to the round rivets embedded in two of the knight’s body armour, and the red tongue of fire on the duke of Braganza’s right shoulder. Notice his right arm and hand is raised in a hailing or greeting gesture.
The plague of locusts (6) can also be found in Alfonso’s armour, his right leg and knee shaped to represent a locust and the folds in St Vincent’s alb its horns.
For the three days of consecutive darkness (7) look to the consecutive line of the three clergymen wearing black hats.
Pestilence of livestock (8): Pistil, instead of pestil, as in the female reproductive part of a flower – and lance instead of lence. No livestock appears in the scene but the three lances point to members of the clergy and infer that the aftermath of conflict, even among popes and bishops can result in the decimation of their flocks. This was a period when there was a schism in the Catholic Church and three popes claimed the chair of St Peter.
Another play on words is the Water to Blood plague (9) and refers to the legs of the two kneeling knights. The biblical passage from Exodus reads: “With the staff in my hands I wil strike the water of the Nile and it will be changed into blood…” The staff is the one held by Afonso, duke of Braganza. Notice its pointed end. The river of blood – the ‘Nile’ – is an anagram of ‘line’. Hence the lined red legs of the two knights.
Finally the remaining plague refers to one of wild animals or flies – the bible describes them as gadflies. I’m still trying to identify the iconography for this plague and will publish it when I locate it.
