Good Friday (Rossetti)
Stone vs. sheep
Biblical stones are hard-hearted, unresponsive. Sheep follow their shepherd. She's asking if she's spiritually dead.
Counting drops
The clinical precision—'number drop by drop'—is the problem. She's observing the crucifixion like a scientist instead of mourning.
Gospel witnesses
Specific references: the women at the cross (Luke 23:27), Peter's denial and tears (Luke 22:62), the repentant thief (Luke 23:40-43). Everyone else responded.
Moses striking rock
Exodus 17:6—Moses struck a rock and water poured out. She's asking Christ to strike her stone heart until tears flow.
