The following flying buttress figurine is the topmost one of flying buttress no. 33. The statues on this flying buttress were carved in 1954 by George van der Wagt, and depict six crippled, blind and lame persons, after the Beatitudes from the Sermon on the Mount. At the top sits a male figure with a beard, in a blessing posture.
This blessing posture is often depicted in Christian art, in particular in icons. I do not know if this posture has a specific name in Christian literature. I know it from the oriental yoga; where this hand gesture is called the Abhaya Mudra: meaning, "No fear'-hand gesture. It is meant to take all fear away from the blessed person. In the West, this gesture has a more general meaning of blessing.
Supreme Commander In Chief
It is not clear to me whom this figure should portray. It's mentioned as 'a prophet’ in the records of the restoration from 1954, but I think it was rather meant to depict God the Father, on his heavenly throne. Perhaps the sculptor meant that the people who suffer are blessed. Van der Wagt was apparently not religious. In a newspaper article from that time he explained that he did not know what the story of the Foolish and Wise Virgins was about. He borrowed a Bible and read the story, 'And that's why now there are women carrying cans of oil all over the church'. So I guess he that he didn't ascribe a higher meaning to this sculpture as much, but made it to complete the series. Perhaps this was also done at the request of the church council, or whoever chose the iconographic themes.
