The Design of the Sixteenth Century Bulwarks of Alghero: the Earthworks of the Military Engineers. This article is part of a Phd research focused on the work of the Palearo Fratino brothers, military engineers in the service of the Crown of Spain in the second half of the 16th century. The proposed study analyzes the plans realized between 1552 and 1578 for the adaptation of the medieval fortifications of Alghero. In the second half of the 1500s the intense activities which were being conducted for the enclosure of the new building “alla moderna” were placed under the direction of Rocco Capellino, an engineer sent to the Island by Carl V. In 1573 Giorgio Palearo Fratino came to Sardinia to replace Capellino with the assignment of proceeding with the work in Cagliari and Alghero according to the design executed by his brother Jacopo in 1563. Giorgio also created a plan for the widening of his brother’s traça and a plan for a fortress on the hill of S. Giuliano, near Alghero; neither of these plans was ever carried out. An elaborate series of designs that represent the ideas of Capellino, Jacopo and Giorgio Palearo shows a different attitude from the planners, in particular between the Capellino and Palearo Fratino, regarding the morphology of the places and the use of geometric matrices. Therefore the present study, introduced through three-dimensional graphical models, analyzes the geometric matrices adopted by the planners in the design of the bulwarks, the correspondence of the plans to the indications of the military treatises and its adaptation to the land (morphology) and the pre-existing medieval structures.

Abstract
The Design of the Sixteenth Century Bulwarks of Alghero: the Earthworks of the Military Engineers. This article is part of a Phd research focused on the work of the Palearo Fratino brothers, military engineers in the service of the Crown of Spain in the second half of the 16th century. The proposed study analyzes the plans realized between 1552 and 1578 for the adaptation of the medieval fortifications of Alghero. In the second half of the 1500s the intense activities which were being conducted for the enclosure of the new building “alla moderna” were placed under the direction of Rocco Capellino, an engineer sent to the Island by Carl V. In 1573 Giorgio Palearo Fratino came to Sardinia to replace Capellino with the assignment of proceeding with the work in Cagliari and Alghero according to the design executed by his brother Jacopo in 1563. Giorgio also created a plan for the widening of his brother’s traça and a plan for a fortress on the hill of S. Giuliano, near Alghero; neither of these plans was ever carried out. An elaborate series of designs that represent the ideas of Capellino, Jacopo and Giorgio Palearo shows a different attitude from the planners, in particular between the Capellino and Palearo Fratino, regarding the morphology of the places and the use of geometric matrices. Therefore the present study, introduced through three-dimensional graphical models, analyzes the geometric matrices adopted by the planners in the design of the bulwarks, the correspondence of the plans to the indications of the military treatises and its adaptation to the land (morphology) and the pre-existing medieval structures.
