I was interested in Celtic knot work and the interweaving of a design in 2D space. I studied Irish art and discovered that the patterns were introduced through Viking trading in Ireland. The Viking metal work was usually made with the metal from coins, jewelry, and other metal objects taken or paid to them as tribute. The surfaces would be decorated in a pattern of interlocking links, and transformed into the use of animal figures contorted in strange positions. The designs became more elaborate and delicate through the years 800-1100 CE and each style is named for the location where it was uncovered.
