		Note that Ignace Pardies dropped the "de." The father died sometime in the period 1640-5.
		Pardies had completed a work on optics when he died, and apparently Ango drew on it for his work on optics published after Pardies' death.
		Pardies caught a fatal disease while carrying out his ministry during the Easter season of 1673 in the hospital for the poor at Bicêtre.

	Artefacts of Time
		Pardies' instrument was placed on the table and carefully levelled using the plumb.
		The sun shining' says Pardies who had a gift for stating the obvious, `turn the meridian plate on its pivot so that the shadow of the circle falls precisely on the axis of the degree of the zodiacal sign or the day of the month corresponding with the time that one is using the instrument.
		Pardies' work in the subject followed on from that of his Jesuit colleague Athanasius Kircher, and from that of the Minim friar Emanuel Maignan.

	Ignace Pardies, S.J.
		Ignace G Pardies, S.J. was born in Pau, France and died in Bicetre.
		Pardies was a temperate and courteous critic of Newton with a vigorous intellect, as is evident from his pedagogical writings and his contacts with the pioneers of geometry.
		Pardies had argued that such a drastic departure from the accepted theory should not be entirely founded on the one experiment of the prism since the radical implication of Newton's paper would overthrow the accepted foundations of geometrical optics.

	Pardies, Globi coelestis, 1674 (Site not responding. Last check: 2007-10-31)
		Pardies was a Jesuit astronomer whose star atlas was published by his colleagues just after his death.
		Pardies' star atlas is stylistically one of the most attractive ever published.
		Pardies took his constellation figures primarily from Bayer's Uranometria, but since each chart covers a large section of the sky, these figures had to be carefully integrated, which was not an easy task.

		Father: Government Position; Guillaume de Pardies was a royal counsellor of the Parlement of Navarre.
		Education: Religious Orders; D.D. It appears that Pardies' entire education, from his entry into the Jesuit college at Pau, was completed within the schools of the order.
		Scientific Societies: Although Pardies was never a member of any scientific society, he kept in contact with members of the Royal Society as well as the Académie.

	Star Tales – Musca Borealis (Site not responding. Last check: 2007-10-31)
		Eventually, though, the northern fly was swatted by astronomers.
		To add to the confusion, the same stars were used in 1674 by the Frenchman Ignace-Gaston Pardies to form Lilium, the fleur-de-lis of France, but that was a very short-lived addition.
		Musca Borealis crawls across this chart from the Uranographia of Johann Bode.

		A significant treatise in the history of optics because it established the outline of a wave theory of light nearly eight years in advance of Huygens' Traité de la lumière (1690).
		Both Ango and Huygens studied the experiments of Jesuit scientist Ignace Gaston Pardies (1636-1673), available in an unpublished manuscript.
		These experiments are believed to have suggested a light wave theory to both Ango and Huygens.

	Pardies, Globi coelestis, 1690 (Site not responding. Last check: 2007-10-31)
		The Pardies star charts included the positions not only of the stars, but of historically important comets.
		This innovation was probably inspired by Lubieniecki's Theatrum, 1666-68, which featured many star maps whose sole purpose was to track significant comets.
		Barely visible just below Virgo is the comet of 1680, sometimes known as Newton's comet, since Isaac Newton published a diagram of its orbit as a frontispiece to his Principia, (1687).

	Zur Farbenlehre
		In any case, it does seem that Newton genuinely believed he was reporting proven facts, not advocating hypotheses.
		When the French Jesuit, Ignace Gaston Pardies, responded to Newton’s paper on colors with a comment on what he (Pardies) called Newton’s “hypothesis” of colors, Newton bristled at the word, and replied
		I am content that the Reverend Father calls my theory an hypothesis if it has not yet been proved to his satisfaction.

	Ch.1 - Event Symmetric Space-Time
		Newton's rival, Robert Hooke, was one of those who wanted an analogous theory of light but he failed to see that light must slow down in dense media rather than speed up.
		In 1673 Ignace Pardies corrected Hooke's oversight and provided a new explanation for Snell's law.
		If light propagated in a direction perpendicular to wave fronts and slowed down as it passed through a dense medium, then waves become closer together and would be deflected in accordance with the sine law.

	Newton's Optical Disputes
		To appreciate many of Newton's writings on optics fully, it is essential to be aware of the contemporary comments and criticisms to which Newton was responding.
		He was particularly incensed at having the accuracy of his observations queried by two French Jesuits, Francis Linus and Ignace Pardies.
		In fact, both men had misunderstood Newton's essay and he had little difficulty refuting them: Linus frankly admitted defeat, and Pardies died before Newton's reply was published.

	Robert Hooke
		Hooke was not alone in challenging Newton’s claim.
		Christian Huygens, Ignace Pardies and the Jesuits of Liege joined Hooke.
		Particularly Hooke and Huygens rejected Newton’s claim that his theory was simply derived with certainty from experiments.
