The 1143 Latin Koran translation ended rather than began serious Islamic study

Evidence

The translation of the Koran undertaken at his expense by the English scholar Robert of Ketton, and completed in July 1143, is a landmark in Islamic studies. With this translation, the West had for the first time an instrument for the serious study of Islam. Its appearance brought the first short period of objective appraisal to a fitting end. But it is an end rather than a beginning. — R. W. Southern, Western Views of Islam in the Middle…, 199
