The Unmercenary Physicians
The brothers practiced medicine as a work of mercy rather than a trade. Their life records that they received the gift of healing and applied it freely, declining all fees, so that they became widely known as unmercenary healers; the Greek term anargyroi, "without silver," attached to them and to the broader company of physician-saints who followed the same rule.
A defining episode concerns a gravely ill woman named Palladia, whom other physicians had given up. After she was healed through the brothers' care, she sought privately to give Damian three eggs "in the Name of the Holy Life-Creating Trinity," and he accepted them out of reverence for that Name. When Cosmas learned of the gift, he took it as a breach of their vow to accept nothing, and on his deathbed asked that his brother not be buried beside him. According to their life, after both had reposed a camel they had once healed spoke with a human voice, explaining that Damian had accepted the gift in honor of God's Name and not out of greed, and so the brothers were laid to rest together.
