Lie bialgebras on k3 and the corresponding Lagrange varieties are classified by means of a pair of quadratic forms on k4, where k is a field whose characteristic is not 2. It turns out that any Lagrange variety is composed of two (possibly degenerate) quadratic surfaces in kP3 defined by the above quadratic forms respectively.
