[EN] This thesis aims to develop a theoretical investigation that identifies the main contributions of the scientific-technical work of Leonardo da Vinci (Vinci, 1452- Amboise, 1519), related to the Project Engineering area of knowledge and especially with two of its nuclear concepts Project and Design or, using the current denomination: Engineering Design and Project Engineering. To this end, an exhaustive review of Leonardo's manuscripts and codices (primary sources) is conducted and then a study of the existing literature on his scientific-technical work (secondary sources) is carried out. Then, various Leonardo's projects are studied relating them to current design / project concepts (ergonomics, ecodesign, analogies, etc.), the coincidence or not of his theories is observed, and the degree of proximity between his methodologies, methods, techniques and tools and those used in the present is determined. Finally, a synthesis of the findings and results presented in the different chapters addressed in the thesis is made, integrating how Leonardo's contributions in relation to graphic techniques, design instruments, document morphology, systemic, rational and experimental thinking, analogical design, experimental validation of design solutions, design based on nature and respectful of the environment, as well as his ability to put functional designs into practice and build them, configure his scientific-technical work as crucial in the development of the discipline of engineering projects. / [ES] La presente tesis persigue desarrollar una investigación teórica que identifique las principales contribuciones y aportes de la obra científico-técnica de Leonardo da Vinci (Vinci, 1452- Amboise, 1519) relacionados con el área de conocimiento de Proyectos de Ingeniería, vinculadas principalmente con dos conceptos nucleares a la misma, Diseño y Proyecto, o utilizando la nomenclatura actual, los conceptos de Diseño en Ingeniería (Engineering Desing, en la literatura en inglés) y de Ingeniería de Proyectos (Project Engineering). Para ello se realiza una revisión exhaustiva de los manuscritos y códices de Leonardo (fuentes primarias) y seguidamente se efectúa un estudio de la literatura existente sobre la obra científico-técnica del mismo (fuentes secundarias). Tras ello, se estudian diversos proyectos de Leonardo relacionándolos con los conceptos de diseño/proyecto actuales (ergonomía, ecodiseño, analogías, etc.) y se observan la coincidencia o no de sus teorías, y el grado de proximidad entre sus técnicas y herramientas, con los métodos, técnicas e instrumentos usados en la actualidad. Finalmente se realiza una síntesis de los hallazgos y resultados presentados en los diferentes capítulos abordados en la tesis, integrando cómo las aportaciones de Leonardo en relación a las técnicas gráficas, instrumentos de diseño, morfología documental, pensamiento sistémico, racional y experimental, diseño analógico, validación experimental de las soluciones de diseño, diseño basado en la naturaleza y respetuoso con el entorno, y su capacidad para llevar a la práctica diseños funcionales y construirlos, configuran su obra científico-técnica como crucial en el desarrollo de la disciplina de los proyectos de ingeniería. / [CAT] La present tesi persegueix desenvolupar una investigació teòrica que identifique les principals contribucions i aportacions de l'obra científico-tècnica de Leonardo da Vinci (Vinci, 1452- Amboise, 1519) relacionats amb l'àrea de coneixement de Projectes d'Enginyeria, vinculades principalment amb dos conceptes nuclears a aquesta, Disseny i Projecte, o utilitzant la nomenclatura actual, els conceptes de Disseny en Enginyeria ("Engineering Desing", en la literatura en anglés) i d'Enginyeria de Projectes ("Project Engineering"). Per a això es realitza una revisió exhaustiva dels manuscrits i còdexs de Leonardo (fonts primàries) i seguidament s'efectua un estudi de la literatura existent sobre l'obra científico-tècnica del mateix (fonts secundàries). Després d'això, s'estudien diversos projectes de Leonardo relacionant-los amb els conceptes de disseny/projecte actuals (ergonomia, ecodisseny, analogies, etc.) i s'observen la coincidència o no de les seues teories, i el grau de proximitat entre les seues tècniques i eines, amb els mètodes, tècniques i instruments utilitzats en l'actualitat. Finalment es realitza una síntesi de les troballes i resultats presentats en els diferents capítols abordats en la tesi, integrant com les aportacions de Leonardo en relació a les tècniques gràfiques, instruments de disseny, morfologia documental, pensament sistèmic, racional i experimental, disseny analògic, validació experimental de les solucions de disseny, disseny basat en la naturalesa i respectuós amb l'entorn, i la seua capacitat per a portar a la pràctica dissenys funcionals i construir-los, configuren la seua obra científico-tècnica com a crucial en el desenvolupament de la disciplina dels projectes d'enginyeria. / Cervero Melia, E.

This thesis examines the situation of the Latin language in the unique linguistic environment of early fifteenth century Florence. Florence, at this time, offers an interesting study because of the vernacular language's growing status in the wake of the literary success of vernacular authors Dante, Petrarch and Boccaccio, and the humanist study of Greek language. Joshua Fishman's theories on threatened languages and Reversing Language Shift are used to examine Latin's position in this environment. Chapter I describes Fishman's theories and applies them to the special situation of Florence, giving a context for the following three chapters. Chapter II offers an original interpretation of Leonardo Bruni's Dialogus ad Petrum Histrum, emphasising the significance of the speaker, Coluccio Salutati, and his apparent message in favour of reviving spoken Latin. Chapter III describes a debate that began in 1435, after the papal Curia moved to Florence and Bruni was drawn into the discussions of the papal humanists. The debate examined whether the Ancient Romans actually spoke Latin in their daily lives, or whether Latin was primarily a written, literary language, and there was a separate, spoken language for domestic environments, as in Florence in the fifteenth century. A number of humanists commented in response to this question. I examine Flavio Biondo's treatise dedicated to Leonardo Bruni, Bruni's letter in response to Biondo, Poggio Bracciolini in the the Tertiae Convivialis Historiae Disceptatio, and finally, Leon Battista Alberti's comment in the preface to the third book of the Della Famiglia. In Chapter IV, Bruni's vernacular writing, the Vita di Dante,is used to establish Bruni's own attitude to language choice as flexible and dependant on the subject matter, genre and intended audience for the work.

This dissertation examines Leonardo da Vinci’s literary writings, namely those known as the Bestiario, Favole, Facezie, and Profezia, as compelling expressions of how Leonardo envisioned the role and influence of morality in human life. Through an analysis of these four literary collections from the perspective of their genre history, literariness, and philosophical dimension, it aims to bring to light the depth with which Leonardo reflected upon the human condition. The Bestiario, Favole, Facezie, and Profezia are writings that have considerable literary value in their own right but can also be examined in a wider historical, literary, and philosophical context so as to reveal the ethical ideas that they convey. By studying them from a historical perspective, it is possible to contextualize Leonardo’s four collections within the tradition of their respective genres (the bestiary, fable, facetia, and riddle) and thus recognize their adherence as well as contribution to these traditions. The literary context brings to light Leonardo’s intentionality and ingenuity as a writer who uses generic conventions in order to voice his ethical views. Assessed from a philosophical standpoint, these four literary collections prove to be meaningful reflections on the moral state of humanity, thereby justifying the characterization of Leonardo as a moral philosopher. Current scholarship on the Bestiario, Favole, Facezie, and Profezia generally views these writings as minor Leonardo works and treats them as ancillary parts of his production. This dissertation, conceiving Leonardo as a moral philosopher, provides interpretations that lead to the conclusion that his thought pervades both his major and minor works and that these literary writings must be viewed as an extension (and result) of Leonardo’s greater notions of the world and of how all parts relate to one another. The Bestiario, Favole, Facezie, and Profezia are works that deserve greater attention reflecting as they do the thought of this Renaissance man.
