Extract from the tale of Briar Rose by the Grimm Brothers:
But round about the castle there began to grow a hedge of thorns, which every year became higher, and at last grew close up round the castle and all over it, so that there was nothing of it to be seen, not even the flag upon the roof. But the story of the beautiful sleeping "Briar-rose," for so the princess was named, went about the country, so that from time to time kings' sons came and tried to get through the thorny hedge into the castle.
But they found it impossible, for the thorns held fast together, as if they had hands, and the youths were caught in them, could not get loose again, and died a miserable death.
