  In this talk we discuss Feynman integrals which are related to elliptic
curves. We show with the help of an explicit example that in the set of master
integrals more than one elliptic curve may occur. The technique of maximal cuts
is a useful tool to identify the elliptic curves. By a suitable transformation
of the master integrals the system of differential equations for our example
can be brought into a form linear in $\varepsilon$, where the
$\varepsilon^0$-term is strictly lower-triangular. This system is easily solved
in terms of iterated integrals.
