     If ${\displaystyle E}$ does not have complex multiplication (CM), by results of Ribet and Elkies concerning fields of definition of elliptic ${\displaystyle \mathbb {Q} }$-curves ${\displaystyle E}$ is isogenous to a curve defined over a polyquadratic extension of ${\displaystyle \mathbb {Q} }$.
