Mathematical Treasure: Jonas Moore's Mathematicks

Frank J. Swetz (The Pennsylvania State University)

Jonas Moore, together with the famous diarist, Samuel Pepys (1633-1703), founded the Royal Mathematical School at Christ’s Hospital, London in 1673. Moore was the Mathematics Master of the school and wrote A New Systeme of the Mathematicks for the use of his students. The book was first published in 1681. The title page of this first edition is shown above.

Chapter IV is devoted to spherical trigonometry. The plate opposite page 100 illustrates various applied trigonometry situations.

On page 101, above, is a listing of propositions for spherical trigonometry.

Here is an illustration and discussion of the employ of a cross-staff in obtaining measurements.

Above is the title page for Book II of Moore’s Mathematicks.
