The Borromean rings consist of three circles which are linked and form a Brunnian link; i.e., removing any ring results in two unlinked rings. In other words, no two of the three rings are linked with each other, but nonetheless all three are linked. Here, they are further linked by a minimal surface, carved by regularly spaced holes.
The name "Borromean rings" comes from their use in the coat of arms of the aristocratic Borromeo family in Northern Italy. The link itself is much older and has appeared in Buddhist art from around the 2nd century. The Borromean rings have been used to indicate strength in unity. In particular, some have used the design to symbolize the Trinity.
