The creation and use of logarithmic rules for calculating will be studied here by the analysis of texts written by William Oughtred: The Circles of Proportion and The Horizontal Instrument (1633), New Line or Artificial Gauging Rod (1633) and The description and Use of the Double Horizontal Dial (1653). Other works of this scholar were examined to show their contribution to the teaching of Mathematics, as the texts Clavis Mathematicae, which was used by more than 70 years, and Mathematical Recreations translated into English and combined by him with other texts, such as: The description and Use of the Double Horizontal Dial and Horological Ring published as appendages of Mathematical Recreations in 1653 / Esta pesquisa aborda obras de William Oughtred (1574-1660), clérigo britânico e instrutor de matemática, a quem se atribui o projeto da primeira régua de cálculo logarítmica linear na Europa no século XVII, quando a elaboração de tabelas astronômicas e calendários utilizados, por exemplo, para orientar navegações, demandava meios para que o cálculo de números extremamente pequenos ou extremamente grandes fosse realizado rapidamente. A criação e o uso de réguas de cálculo logarítmicas foram aqui estudados pela análise dos textos The Circles of Proportion and The Horizontal Instrument (1633), New Artificial Gauging Line or Rod (1633) e The Description and Use of the Double Horizontal Dial (1653), escritos por William Oughtred. Outras obras desse estudioso foram examinadas para mostrar a sua contribuição para o ensino da Matemática, como os textos Clavis Mathematicae, que foi utilizado por mais de 70 anos, e Mathematical Recreations traduzido para o inglês e incrementado por ele com os textos The Description and Use of the Double Horizontal Dial e Horological Ring publicados como apêndices de Mathematical Recreations, em 1653
