  The bisection of trapezoids by transversal lines has many examples in
Babylonian mathematics. In this article, we study a similar problem in Elamite
mathematics, inscribed on a clay tablet held in the collection of the Louvre
Museum and thought to date from between 1894--1595 BC. We seek to demonstrate
that this problem is different from typical Babylonian problems about bisecting
trapezoids by transversal lines. We also identify some of the possible
mathematical ideas underlying this problem and the innovative approach that
might have motivated its design.
