Bind rune
Ligature of two or more runes / From Wikipedia, the free encyclopedia
A bind rune or bindrune (Icelandic: bandrún) is a Migration Period Germanic ligature of two or more runes. They are extremely rare in Viking Age inscriptions, but are common in earlier (Proto-Norse) and later (medieval) inscriptions.[1]
On some runestones, bind runes may have been ornamental and used to highlight the name of the carver.[2]
