    A circulant is a Cayley graph of a cyclic group. Arc-transitive circulants of square-free order are classified. It is shown that an arc-transitive circulant Gamma of square-free order n is one of the following: the lexicographic product Sigma[(J) over bar (b)], or the deleted lexicographic Sigma[(K) over bar (b)]-b Sigma, where n = bm and Sigma is an arc-transitive circulant, or Gamma is a normal circulant, that is, Aut Gamma has a normal regular cyclic subgroup.
