Wikipedia
Lacertines, most commonly found in Celtic Art, are interlaces created by animal forms. Interlaces are a two-dimensional decoration formed by a number of ribbons or straps woven into a complex, usually symmetrical design. The art is intricate, often incorporating animals into the elaborate twisting knots, and maze-like weavings. Some of the most common animals used in lacertines are snakes, birds, lions, and dogs.
