The large Jelling rune stone from the 10th century was raised by King Harald Bluetooth in memory of his father Gorm and his mother Thyra, and in celebration of the conquest of Denmark and Norway and the conversion of the Danes to Christianity. and thus sometimes called “Denmark’s birth certificate”. Somehow King Harald Bluetooth became known as a great communicator and has thus given name to today's open wireless protocol for data exchanging used by computers and cell phones, the Bluetooth. So this is, in fact, the first bluetooth transferred data. The futhark runic text: "King Haraldr ordered this monument made in memory of Gormr, his father, and in memory of Thyrvé, his mother; that Haraldr who won for himself all of Denmark and Norway and made the Danes Christian." To see side of the stone with the figure of Jesus, search for: BDGTKP or HT72CD. Actually the stone has three sides.
