Roundel with Saint John on Patmos with Apocalyptic Vision 1520 - 1530

This roundel, created by Dutch painter Dirck Vellert between 1520 and 1530, depicts Saint John on the island of Patmos receiving his apocalyptic vision. The stained glass artwork portrays Saint John writing in his book as an eagle, representing the Holy Spirit, dictates to him. Above, God the Father appears in heaven with angels, while a seven-headed dragon with a woman crowned with stars represents the forces of evil. This roundel is a vibrant example of the early Netherlandish tradition of stained glass and highlights the ongoing struggle between good and evil.
