Leaf from an illuminated French Book of Hours

Translation of Latin text:
Through Christ they will be freed from tribulations.
Of St. Nicholas, Bishop.
Nicholas, the friend of God, adorned by a priestly [mitre],
showed himself loving to all.
V: . Blessed Nicholas, pray for us.
R: . That we may be made worthy of
the promises of Christ: Let us pray.
Prayer: . O God, who [adorned] blessed Bishop Nicholas, your priest,
[with countless miracles] . . . .
