Abstract: We describe a tabulation of (conjecturally) modular elliptic curves over the field Q(sqrt{5}) up to the first elliptic curve of rank 2. Using an efficient implementation of an algorithm of Lassina Dembélé, we computed tables of Hilbert modular forms of weight (2,2) over Q(sqrt{5}), and via a variety of methods we constructed corresponding elliptic curves, including (again, conjecturally) all elliptic curves over Q(sqrt{5}) that have conductor with norm less than or equal to 1831.
