        A knot in its original sense can be modeled as a mathematical knot''' (or link) as follows: if the knot is made with a single piece of rope, then abstract the shape of that rope and then extend the working end to merge it with the standing end, yielding a mathematical '''knot'''. If the knot is attached to a metal ring, then that metal ring can be modeled as a trivial '''knot''' and the pair of '''knots''' become a link. If more than one mathematical ' knot (or link) can be thus obtained, then the simplest one (avoiding detours) is probably the one which one would want.
