Vino a su vez. Lo hizo repetidas veces. Yo amaba a una mujer Hoy es 17 de Octubre Voy, pues, a entablar una insensata lucha con el invierno. Reina un silencio sepulcral, un silencio absoluto. No se oye ni canto de ave, ni rumor de corriente, ni suspiro de brisa, ni columpio de planta La humedad del aire se convierte en agujas de hielo que punzan mi semblante. Un invierno en Spitzberg da una idea de la eternidad en el infierno. Dudo hasta de mi propia existencia.

Yo no he perdido la esperanza, sino la realidad. Hacia cualquier parte que dirijo el pensamiento, disto de la humanidad centenares de leguas. Mil quinientas millas al Occidente se halla la Groenlandia, [] continente de hielo que enlaza dos mundos Pero no Estoy en San Petersburgo. Es una tarde de Mayo. Tomamos el sol en embalsamados jardines. This is the Greek title of the Book of Revelation.

Camina muy de prisa. Parece una blanca paloma venida de otros horizontes a visitar un mundo olvidado por el Criador El cielo aparece negro al lado de la reverberante claridad de la luna y de la nieve. Las estrellas se ven tan lejos y tan atenuadas que parecen, pertenecer a otros mundos. Acurrucado frente a [] la hoguera paso unas horas sin medida He visto el mundo y la sociedad tan a lo lejos, en tan graduada perspectiva, que he adquirido el conocimiento exacto de todas las cosas.

Transferring this angular measure to the saltarregla, he can improve the control of the dressing process by the squaring method.

When using plantas al justo, that is, full templates, the problem involves the rotation of the entire template, a method known in nineteenth century Descriptive Geometry treatises as rabattement. When the intrados joint is orthogonal to the face arch, the mason can solve the problem easily, transferring the distance between two consecutive intrados joints, taken from the elevation, to the template By contrast, when the intrados joint is oblique, the problem is not so simple.

As for flexible templates for spherical or torus surfaces, they are completely lacking in the early sixteenth century stonecutting tracings in Murcia cathedral [FIG. They are. In any case, along the sixteenth century this subject is under the command of stonemasons and architects, or more precisely, a peculiar group between both professions.

This practice does not exclude the interest of architects in this matter; Alonso de Vandelvira lent a copy of his manuscript to Juan de Valencia; after the death of the latter, he supposed it was in the hands of Juan de Herrera, Francisco de Mora or Juan de Vega The borderline position of this group of professionals did not make their life easy. In , Pedro de Velasco tried to exclude Rojas from the decisions about fortification arguing that he was just a stonemason; however, in , Rojas reversed the argument showing with pride his building experience, which granted him authority to give his opinion in constructive matters Otherwise the architect would be at the orders of the workmen, which would be tantamount to placing the cart before the horses That is, a new form of knowledge is appearing, using classical science in order to solve practical problems, in contrast with Antique and Mediaeval science, that usually do not seek their application to practical problems This program, favoured by the Spanish crown in the last decades of the sixteenth century, will be developed slowly; the cycle will be closed not in Spain, but rather in FIG.

Continental Europe. Other texts, such as Ms. However, the lack of didactic intentions in Guardia or Ms. Although it is not a specialised stonecutting manual, but a general architectural treatise, it includes two full books, about pages, to stonecutting; this allows a comprehensive and detailed approach to our subject, in contrast with Rojas This silence was broken in , when Girard Desargues, a bourgeois from Lyons, amateur architect and precursor of Projective Geometry, published a leaflet offering a general method for the resolution of all stonecutting problems [FIG.

The masons of Paris responded violently against this interference from a stranger to the craft; Jacques Curabelle, the best stonecutter of the period, published pamphlets with such Baroque titles as Foiblesse pitoyable du sr G. The confrontation brought about a remarkable contest: two teams of stonemasons, directed by Desargues and Curabelle, were to build arches according to the methods of their leaders. The winners were to receive a substantial prize of one hundred pistoles At the end the competition did not take place, since the contestants did not agree in the rules or the jury. Desargues argued with scorn that geometricians should not be judged by masons; quite to the contrary, the geometricians are the masters and the masons the disciples.

However, this failed duel indicates a change of paradigm: for Desargues the criterion of the validity of stonecutting methods does not lie in the apparent perfection of the final built piece, but rather in the mathematical correction of the methods used in its execution. The consequences of this paradigm shift were felt slowly, although gradually.

The confrontation led to the appearance of three stonecutting treatises in a few years. Templates, voussoirs and interior space in an arch opened in a curved wall. Arches opened in curved walls.

Only in the second and third volumes he explains actual stonecutting problems, placed under the heading of tomotechnie. In this way, the discipline is put under the rule of geometry, including demonstrations for each particular problem, in contrast with previous treatises. His procedure was not restricted to stonecutting, not even to construction. Rather, he presented it FIG. Projection planes, ground line and projections of a straight line.

Only when adding a second projection, we can determine unambiguously this point; the passage suggests implicitly that the striking auxiliary projections used by stonecutters are unnecessary While double projection, as used up to this period, allows to determine the position of a point in relation to other objects, the ground line furnishes a method for computing the absolute position of a point. At the same time, it fixes in space the position of both projection planes; this allows the draughtsman to represent any plane through its intersections with the projection planes The use of planes is not really very useful in stonecutting tracings; up to this moment, nobody has built a plane or a straight line, but rather finite elements.

In this way Monge implies a subtle inversion of the concepts used in our subject up to this moment; the introvert drawing of stonemasons, timely transferred to scientific language, comes second, while pride of place is taken by the transmission of the orders from the engineer to the executors. Anyhow, we shall deal with the reasons of this evolution, in particular with the exclusion of perspectives, both lineal and cavalier, from the education of engineers, in the next section.

As shown by Alonso et al. That is, writers consider that orthogonal projections and its auxiliary methods — rotations, developments, and the like — are quite useful for the determination of the true shapes of voussoir faces or the angles between their edges, but they do not show intuitively the volume of construction members or their parts. This mission is entrusted to cavalier or linear perspectives. Probably Monge and his aides understood that orthogonal projections were sufficient to show the volumetric structure of these members, or maybe they were trying to put pressure on students so they could read easily plans and elevations showing complex forms Anyway, some details hint that Monge was not the first one to tread that path.

At first sight, the interest of engineers in shadows, while. At this point, we should ask ourselves about the reason of the interest of engineers in stonecutting. However, these explanations [FIG.


Treatises also deal with sloping arches; in particular Martinez de Aranda presents six variants: escarpment or counterscarp, and their combinations with straight plan, or two kinds of obliquity. Such arches seem to deny the military function of the wall, which does not foster the presence of openings.

However, the small size of the arch suggests that it is easier to place in the voussoirs of a round arch in the wall and give them the slant required by the slope of the wall and the skew shape of the arch by means of a simple retouching, rather than addressing the complexities of the template construction methods proposed by the treatises.

Admittedly, treatises also include vaults and stairs; however, in Early Modern military constructions the former are executed on many occasions in brick or concrete, while the stairs are usually relatively members, such as the straight newel helical stair, known in Spain as Caracol de husillo, or at most a member with a helical newel, known as Caracol de Mallorca. All this suggests that the teaching of Stonecutting Theory in military schools focused not so much in the training of engineers for stone construction, but on the education of their spatial vision As Sakarovitch said, the stonemason works on mass, starting from a three-dimensional object, by contrast with the carpenter or the coppersmith, who work on lines or developable surfaces.

This leads to a parallel between the material activity of the stonemason and the abstract position of the geometrician, shown by rich repertoire of developable and warped that can be materialised by the stonemason and their complex intersection On its turn, this geometrical wealth is reflected in the wide variety of graphic techniques used in stonecutting tracings: projections, developments, rabattements, rotations, changes of projection plane. Even the noFIG.

Side view. And finally, the economy and elegance of stonecutting tracings had to be enticing to the military by force All this is what explains, beyond its practical application, the interest of engineers in stonecutting.
