The scenes on the cover are as follows: Each has a legend on a scroll explaining its meaning:
1. Procopius standing before the Saint offering her a casket of jewels.
2. The Saint standing before a small building, representing the house of ill-fame to which, on her refusal to marry, she has been consigned by the judge; Procopius lies apparently dead on the ground and the devil is about to carry him off.
3. St. Agnes has compassion upon Procopius and raises him to life, and dismisses him with an exhortation.
4. Sempronius and Aspasius, the two judges of the Saint.
5. The martyrdom of St. Agnes in the presence of Aspasius. The fire being ineffectual to kill her, though the executioner has to ward off the heat from himself with his hand; he then puts her to death by driving a spear into her neck, and she expires.
The remaining scenes are on the bowl:
6. The burial of the Saint. The body on a bier is covered with a pall having a plain cross upon it; a priest asperges the body and an acolyte stands by with a cross.
7. Scene at the tomb of St. Agnes, in which her sister, St. Emerentiana, is being stoned to death by three men.
8. The Saint with other martyrs appearing to her relations at her tomb.
9. The sick Princess Constantia lying on the tomb of St. Agnes, who appears to her.
10. The Princess Constantia, healed of her sickness, kneels at the feet of her father, the Emperor Constantine.
Within the cover beneath the finial is a circular disc in a raised setting enamelled in the same manner with a half-length figure of Our Lord in Glory, holding a chalice, and with other hand raised in benediction. A corresponding medallion in the bottom of the bowl has a beautifully designed subject of St. Agnes kneeling before an old man, her father or her judge. She hols a book in her hands.
On the lower part of the stem are the symbols of the Evangelists with their names on scrolls. The figure of the angel representing St. Matthew is of exceptional beauty, and being on a much larger scale than is possible in the scenes on the cup, the modelling of the features is full of character.
