I rephrased it to: "The European Reinassance was essentially the assimilation of the cultural wealth amassed by the Islamic empire." This is more accurate. But I think their influence was much more far reaching than just passing on Greek literature: - Before paper, parchments were used. A bible took 3000 sheep or goat to print. - They adopted Indian numerals and adapted them to the form we use today. Imagine Copernicus calculating trajectories of planets with Roman numbers. - Nicolaus Copernicus started his studies using almanacs and tables such as the Alfonsine tables, the tables were originally in Arabic and were collected/translated by Alfonso X of Castile in Toledo. They included observations ranging from the days of Ptolomy onwards. - Many Western discoveries came from innovations in optics (e.g: telescope, microscope). The Islamic empire did great contributions to the field of optics. They experimented with reflection, refraction, lenses, etc... and that is original work with literature to support it.
