Nevertheless, it is not known exactly when Pacheco met his teacher, the greatest master of Spanish fencing, Jerónimo Sanchez de Carranza.

This book describes a number of secrets, principles and prescriptions, with the help of which anyone can learn and teach others without resorting to the instructions of other masters.

As a pupil of Carranza, Pacheco de Narváez reproduces in detail the inventor's characteristic methods and explains the curious schemes, with drawn circles and positions of the blades relative to each other – in the form of conditional swords,[clarification needed] intersecting at different angles depending on the type of movement, the cutting or piercing stroke.

Fencers need to take a stand outside the distance in order to systematize the general concept of the right distance, Carranza and his follower Narváez represent[clarification needed] a circle drawn on the ground – "circonferencia imaginata entre los cuerpos contrarios" an 'imaginary circumference around the opposing bodies', which further outlines the actions.

[28][29] Modo fácil y nuevo para examinarse los maestros en la destreza de las armas ('A simple way of examining teachers in the art of fencing with weapons') is another of Pacheco de Narváez's most famous works (a dialogue between a pupil and an exam teacher on the philosophy and art of fencing).

The book at that time was published by the Cabinet of Lazaro de los Ríos, Secretary of the King of Spain, dated 26 February 1625 in Madrid.

[34][35] Pacheco de Narváez received gratitude from the king and was appointed examiner for all fencing teachers; however, instead of passing the exams, apparently, his comrades decided to unite against him.

It says the following: Teachers of martial arts are suing Don Luis Pacheco de Narvaez, who must take the exam from all teachers.The protective pillars described in the treatise meet the requirements, correspond to the laws of justice and peace in the Republic.

And above all, absurd[clarification needed] talent and a lack of courage lead to a loss of hope to achieve what is possible, says Pacheco de Narváez.
