Good Friday: Crown of Thorns
According to Gospels, a woven crown of thorns was forcibly placed on Jesus head prior to his crucifixion. The crown was a weapon to torture Jesus as well as to mock him. The crown was in reference to Jesus being the King of the Jews.
The above wooden sculpture was on display at the Victoria and Albert museum. It is carved from oak, made around ca. 1500-1520 by an unknown artist. This wooden sculpture is big so it is probably a standalone rather than an alter-piece.
