The fanciful Celtic knot design "Aillil" is a digital scan of a wonderful sterling silver pendant done by Celtic Spirit.  Celtic Spirit's definition of the Aillil is:  "The Aillil design displays a closed circle symbolic of eternity surrounding a perfect endless knot, also symbolizing eternity.  Together these two symbols represents love in its ultimate and highest form; a constant unchanging eternal love.  The symbol of the ideal state of all lovers."  Visit Celtic Spirit and view their wonderful interpretations of Celtic knot work at:  http://www.celticspirit.com
