His principal work is his 1555 commentary, Ad leges tauri commentarium absolutissimum, on the Leyes del Toro. These were a set of laws promulgated in Toro governing matters of marriage and inheritance, which remained in force in Castile until the entry into force of the civil code of 1888/89. Gómez's commentary became the most important source for that area of Spanish law, and remained in print until 1780.
