 Rudd put his name to two texts on geometry, "Practical Geometry", in two parts (London, 1650), and an edition of Euclid's "Elements" under the title "Euclides Elements of Geometry, the first six Books in a compendious form contrasted and demonstrated, whereunto is added the Mathematical Preface of Mr. John Dee" (London, 1651), but both works show extensive appropriation (without attribution) from Dutch sources of the early 1600s.In particular, Rudd's selection of a hundred questions is largely, but not exclusively, culled from the compilation of Sybrandt Hanszoon van Harlingen (Cardinael) (1578–1647), "Hondert Geometische Questien [A Hundred Geometrical Problems]", published c. 1612.He wrote the supplement to "The Compleat Body of the Art Military", by Lieutenant-colonel Richard Elton, London, 1650; 2nd edit.
