What kind of thorns where on his head?

The thorns on his head were likely from a plant known as the crown of thorns, which is often associated with the crucifixion of Jesus Christ. This plant features sharp, elongated thorns that can inflict pain and symbolize suffering and sacrifice. The crown was used as a form of mockery, meant to insult and belittle. Its imagery has since become a powerful symbol of humility and redemption in Christian theology.
