Another torture Saint Paraskevi endured was when she was thrown into a cauldron of boiling oil and pitch. Noticing Saint Paraskevi remained unharmed, the Emperor came closer to inspect the heat of the cauldron.
Some hot liquid burned his eyes.
The Emperor asked Saint Paraskevi for her to heal his eyes, and she Prayed and healed him through Christ. The Emperor then ceased torturing her and became a Christian.
