A late edition (1st ed.: 1556) of one of the four great English books on land surveying of the 16th century. Digges’s Tectonicon was by far the most successful and long-lived; there were at least twenty editions, the last published in 1692.

Digges (ca. 1515-59?), who attended University College, Oxford, wrote this work for “surveyors, ‘landmeters,’ joiners, carpenters, and masons. It taught the measurement of land, the calculation of quantities, and the use of various instruments such as the carpenter’s rule, the square, and a version of the cross-staff (‘the profitable staff’). Digges was at pains to correct common errors practised by those without an adequate grounding in mathematics; this theme of ‘vulgar errors’ became standard in many subsequent mathematical texts…The work also marks the public début of the commercial trade in mathematical (‘scientific’) instruments in England.”–ODNB.

❧ D.S.B., IV, p. 97. Richeson, English Land Measuring to 1800: Instruments and Practices, p. 53–“The first five chapters give simple rules and methods for the use and application of arithmetic and geometry to the measuring of the areas of simple geometric figures; the remaining sixteen chapters, including the appendix, are primarily an application of the principles outlined in the first five chapters, along with the use and application of the various instruments at the command of the land measurer, carpenter, and artisan”–(& see pp. 52-67 for a full discussion of the instruments described by Digges).
