What is the term for the knot fastening the bride's tunic?

The term for the knot fastening the bride's tunic is known as the Nodus Herculeanus. This specific knot was traditionally used in Roman weddings and held significant cultural symbolism. It was associated with Hercules, a figure emblematic of strength and protection, thus infusing the marriage ceremony with the hope for a strong and prosperous union.

The Nodus Herculeanus was not merely a practical fastening; it represented the sanctity and binding nature of marriage, lending the event a deeper significance within Roman customs. The other terms listed, while related to Roman marriage and ceremonies, do not specifically refer to the knot itself. Sponsalia refers to the engagement period and promises made between the couple. Flammeum pertains to the veil worn by the bride, adding to her appearance during the ceremony. Quando tu Gaius ego Gaia is a phrase representing the vows made by the couple, indicating mutual commitment without mentioning the knot.
