In 1260, Nasir al-Din al-Tusi developed innovative planetary models that included the Tusi couple, allowing for the representation of planetary motion without equants. This advancement in astronomical theory marked a significant contribution to the field of science, influencing later European astronomers. Al-Tusi's work laid the groundwork for future developments in understanding celestial mechanics and the movement of planets.

Nasir al-Din al-Tusi's planetary models developed in 1260 improved astronomical understanding, influencing cosmological poetry during the Scientific Revolution. Poets like Galileo Galilei later drew on these ideas to explore humanity's place in the universe, merging scientific inquiry with poetic imagination.
