"Jesus' crown of thorns was a different story. The most basic of materials wrapped around in the shape of a circle only to be pressed into His holy head.
A crown is a symbol of royalty and honor, but the crown of thorns was created with the opposite intent. The goal was to humiliate and dishonor Jesus, to cause Him pain, and make Him bleed."

"After Jesus’ sham trials and subsequent flogging, and before He was crucified, the Roman soldiers “twisted together a crown of thorns and set it on His head. They put a staff in His right hand and knelt in front of Him and mocked Him. ‘Hail, king of the Jews!’ they said” (Matthew 27:29; see also John 19:2-5). While a crown of thorns would be exceedingly painful, the crown of thorns was more about mockery than it was about pain. Here was the “King of the Jews” being beaten, spit upon, and insulted by presumably low-level Roman soldiers. The crown of thorns was the finalizing of their mockery, taking a symbol of royalty and majesty, a crown, and turning it into something painful and degrading."

"Crown of Thorns, wreath of thorns that was placed on the head of Jesus Christ at his crucifixion, whereby the Roman soldiers mocked his title “King of the Jews.” The relic purported to be the Crown of Thorns was transferred from Jerusalem to Constantinople by 1063. The French king Louis IX (St. Louis) took the relic to Paris about 1238 and had the Sainte-Chapelle built (1242–48) to house it. The thornless remains are kept in the treasury of Notre-Dame Cathedral in Paris; they survived a devastating fire in April 2019 that destroyed the church’s roof and spire."

"Jesus Christ’s crown of thorns was among prized relics saved from the inferno in Notre Dame cathedral in Paris, but how did it get there?
Could the object Christians regard as among the most sacred of religious artefacts really have sat atop Jesus Christ’s head as he was crucified more than 2000 years ago?
As Christians around the world mark the anniversary of Christ’s death and resurrection, it is worth looking at the origin of the crown of thorns and Christ’s cross, a piece of which was also said to be inside Notre Dame."
