Firmitas Cufflinks
These gorgeous cufflinks depicts the "Hercules knot," and are modeled after the ornate clasp of a second century AD Roman bracelet.
The Hercules knot originated in the ancient world. As a knot that would tighten and thus become even more stable when pulled, it quickly became a symbol for a strong bond, and thus a symbol for love, marriage, and commitment. It is the origin of the phrase "tying the knot" when referring to marriage!
"Firmitas" in Latin means tenacity, strength of mind, and the ability to stick to one's purpose.
