The basis for such procedures would have been the 'abacus mathematics' he learnt as a boy." His source for this information is Antonio Manetti's Life of Brunelleschi." A search of Manetti's biography found

In fact, there is some doubt expressed by the editor, Howard Saalman, that Brunelleschi ever went to Rome, and that this passage was added to enhance the stature of Manetti's subject. Also according to Kemp, Leonardo recorded in the Codice Atlantico a cross-shaped measuring staff which he called the bacolo of Euclid, which was used to establish similar triangles. This instrument was perfected in the sixteenth century as the radio astronomico by the geographer and astronomer Gemma Frisius, who commends it for terrestrial as well as astronomical measurements....
