The love knot, also known as the Hercules knot, is a symbol of everlasting love and commitment. In ancient times it was used to symbolise marriage, and it is believed that the phrase 'tying the knot' came from this tradition.
In ancient Greece and Rome, the love knot had a symbolic role within wedding ceremonies. The groom would untie the knot worn within the bride's wedding gown, representing the beginning of their marriage. This tradition may originate from the legendary capture of Diana's girdle by Hippolyta, the Amazon queen.
