Anglo-Saxon runes are runes used by the early Anglo-Saxons as an alphabet in their writing. The characters are known collectively as the futhorc (or fuþorc), from the Old English sound values of the first six runes. The futhorc was a development from the 24-character elder futhark. Since the futhorc runes are thought to have first been used in Frisia before the Anglo-Saxon settlement of Britain, they have also been called Anglo-Frisian runes. They were likely used from the 5th century onward, recording Old English and Old Frisian.
