 Crown of thorns
    our Lord was crowned with a, in mockery by the Romans (Matt.
    27:29). The object of Pilate's guard in doing this was probably
    to insult, and not specially to inflict pain. There is nothing
    to show that the shrub thus used was, as has been supposed, the
    spina Christi, which could have been easily woven into a wreath.
    It was probably the thorny nabk, which grew abundantly round
    about Jerusalem, and whose flexible, pliant, and round branches
    could easily be platted into the form of a crown. (See THORN
