We show that the Laurent series of the two-loop kite integral in D = 4 − 2ε space-time dimensions can be expressed in each order of the series expansion in terms of elliptic generalisations of (multiple) polylogarithms. Using differential equations, we present an iterative method to compute any desired order. As an example, we give the first three orders explicitly.
