English astronomer, mathematician, ethnographer, and translator (1560-1621). He is now credited as the first astronomer to draw an astronomical object after viewing it through a telescope: he drew a map of the Moon on July 26, 1609, preceding Galileo by several months. Handwritten mathematical formulas, circa 1600, on a 7.5 x 4.5 off-white sheet somewhat irregularly clipped from a larger piece (rounded corners) affixed to a 9 x 6.5 off-white partial album page. Harriot pens 15 lines of notes, figures and equations for a “Magneticall Experimente.” In very good condition, with scattered moderate toning, not affecting legibility, several light brushes to equations, and some light show-through from non-related slips and a silhouette on reverse.
Harriot was a tutor of Sir Walter Raleigh and is credited with having made significant theoretical and practical contributions to a variety of scientific disciplines. Harriot—famous for his mathematical work in algebra and for determining that every equation may be regarded as formed by the product of as many simple equations as tehre are units in the number expressing its order—is also believed to have independently developed an astronomical telescope around the same time as Galileo and observed Jupiter’s moons and sunspots. Other research included ballistics, gravity, and navigation—and as an early explorer accompanied Raleigh to North America and surveyed Virginia in 1585, mapping its topography, observing the natural wildlife, and working on a translation of the Algonquian language. The English pioneer of science and mathematics published only one book in his lifetime, but prepared a large number of manuscripts on various scientific subjects, of which these mathematical formulas on magnetism were once a part. Many of his manuscripts have only recently been rediscovered and are now the basis of historical research, with these significant scientific artifacts capturing the wondrous thought process displayed by the advanced thinker.
