The mezzotints are on copper, the relief etchings on zinc. Copper stands for the sun, zinc for the moon. I prepared my ink mixing five different blacks: carbon black, bone black, Japanese charcoal, black iron oxide and Japanese stone black.

At the end Mary looks down upon the city, her face scarred, but merciful.
