The astrolabe, an ancient astronomical instrument, was introduced into European navigation around 1322, enhancing the ability to measure the altitude of celestial bodies. This innovation was particularly significant for maritime exploration, allowing sailors to navigate more accurately. The astrolabe's use spread among navigators in Mediterranean ports, facilitating trade and exploration.

The astrolabe's introduction influenced poets by expanding the themes of exploration and discovery in literature. Poets began to reflect on the human experience of navigating both the physical and metaphysical worlds, as seen in the works of later poets like Christopher Marlowe, who explored themes of ambition and the quest for knowledge.
