It is only rather recently that science has begun to make peace with its magical roots. Until a few decades ago, it was common for histories of science either to commence decorously with Copernicus's heliocentric theory or to laud the rationalism of Aristotelian antiquity and then to leap across the Middle Ages as an age of ignorance and superstition. One could, with care and diligence, find occasional things to praise in the works of Avicenna, William of Beckham, Albertus Magnus, and Roger Bacon, but these sparse gems had to be thoroughly dusted down and scraped clean of unsightly accretions before being inserted into the corners of a frame fashioned in a much later period.
