 Spectroscopy
This concept of light is an old one: in the thirteenth century, Theodoric of Freiburg proposed a theory of the rainbow, according to which rain left tiny droplets of water in the air that bent light.
The accomplishments of Theodoric of Freiburg are told in James Burke's The Day the Universe Changed, in both the TV series and the companion book (Little, Brown; 1985).
Burke, in turn, draws upon William A. Wallace's The Scientific Methodology of Theodoric of Freiburg (Freiburg: The University Press, 1959).

 Blas' Personal Page: The Scientific Method
The scientific method, as we know it, was first employed during the beginning of the fourteenth century by a German Dominican of the name of Theodoric of Freiburg.
The most important thing they learned from the Arabic libraries was that the natural world could be studied and that general principles, now referred to as laws, could be deduced that described the way nature behaved.
In Theodoric's case, he had the hypothesis that the rainbow might be caused by the interaction of light and water.

 Burke - Wolrds Without End
As the questioning grew, stimulated by the flood of information arriving from the Arab world, knowledge became institutionalized with the establishment of the European universities, where students were taught to think investigatively.
The first tentative steps towards science were taken by Theodoric of Freiburg and Roger Bacon.
The logical end to this activity was apparent in the work of the late scholastics, such as Theodoric of Freiburg, Roger Bacon and Bishop Grosseteste, all of whom subjected nature to the same dialectical inquiry.

 Review & comments page: The Measure of Reality   (Site not responding. Last check: 2007-10-12)
Competition for wealth spurred the need for quantification, measurement, and the search for raw materials for currency, building, etc. That seemed to be it for his theories of why.
The rest of the book is vignette after vignette of the progress in counting, measuring, a little about maps, etc. I'm sure Guido of Arrezo, St Isidore of Seville, Marsilio Ficino, Theodoric of Freiburg, and Simon Stevin were swell people.
But simply brief mentions of their contributions to western thought in a long line of other equally obscure names makes for a very boring and pretentious book.

 History of Dogma - Volume VI (ii.ii.ii.i)
The same is true of David of Augsburg and Theodoric of Freiburg.
For a century and more, the work of bringing about an inward conversion of the laity in Germany was carried on, and it was quite specially by Mendicant monks, chiefly Dominican, that this service was rendered.
While in the Romanic lands the Mendicant Orders grew weaker, and in Germany the religious life, still through their influence partly, slowly advanced, the world-ruling Church pursued a course of complete self-abandonment at Avignon, and seemed to have the deliberate wish to subject the ecclesiastical fidelity of the already imperilled piety to the severest test.

Isaac Newton's experiments with prisms are included, but earlier experiments by Theodoric of Freiburg are not; nor are ghostly moonbows, rare fogbows, and ground-hugging dewbows.
Still, this is a brilliantly rainbow-hued, tightly focused investigation of these seemingly miraculous spectacles that inspire wonder and delight in all who view them.

Al-Haytham's ideas were developed by Kamal al-Din al-Farisi (d.1320), who used them in a series of experimental studies which demonstrated, among other things, that the rainbow consists of two refractions and a reflection of light within a water droplet.
Al-Haytham's work was widely known to the early medieval theologian-scientists, including Bacon, Grosseteste and Theodoric of Freiburg (who independently replicated al-Farisi's rainbow experiment in about 1304).
