The Knot of Hercules, also known as Heracles Knot, Love Knot, and Marriage Knot, is a well-known Roman and Greek protective charm. This sturdy knot, formed of two entwined strands, was an important component of a Roman bride’s wedding gown. The Knot of Hercules became symbolic of a happy and productive marriage since Hercules was regarded as the guardian of wedded life. It was fastened around the bride’s waist and only her husband could untie it. The Knot of Hercules was employed as a love token throughout medieval times because it symbolizes lifelong love and loyalty.
