This Demonstration reconstructs de Decker-Vlacq's table of common logarithms from *Arithmetica Logarithmica* (1628). The table consists of logarithms for numbers from 1 to 100000, 150 on each page. A page consists of three columns, each of 50 lines. A line consists of the number , calculated to 10 decimals, and the difference .
