Abstract: We show that a convex subset $ K$ of a linear space is a simplex if and only if it is line compact and every nonempty intersection of two translates of $ K$ is a homothet of $ K$. This answers a problem posed by Rosenthal. The proof uses a reformulation of this problem in terms of Archimedean ordered spaces
