I will review analytic SU(2) Yang-Mills solutions with finite action on de Sitter space from a new perspective. As a byproduct, all abelian solutions are classified and related with rational electromagnetic knots in Minkowski space. In the Yang-Mills case, the gravitational backreaction is easily taken into account as well.
