De re aedificatoria () is a classic architectural treatise written by
Leon Battista Alberti between 1443 and 1452. Although largely dependent on
Vitruvius'
De architectura, it was the first theoretical book on the subject written in the
Italian Renaissance and in 1485 became the first printed book on architecture. It was followed in 1486 with the first printed edition of Vitruvius.
Alberti’s
Ten Books consciously echoes Vitruvius' writing, but he also adopts a critical attitude toward his predecessor. In his discussion, Alberti includes a wide variety of literary sources, including
Plato and
Aristotle, presenting concise version of
sociology of
architecture. Unlike Vitruvius's book, Alberti's tells architects how buildings should be built, not how they were built.
De re aedificatoria is subdivided into ten books and includes:
- Book Five: Works of Individuals
- Book Seven: Ornament to Sacred Buildings
- Book Eight: Ornament to Public Secular Buildings
- Book Nine: Ornament to Private Buildings
- Book Ten: Restoration of Buildings
In his survey of desirable floor plans for sacred buildings— "temples" in his phrase— Alberti begins with the ideal form of the circle, which is expressed in numerous examples of Nature. Nine ideal centrally-planned geometrical shapes are recommended for churches; besides the circle he lists the square, the hexagon, octagon, decagon and dodecagon, all derived from the circle, and, derived from the square, rectangles that exhibit the square and a half, square and a third and double square, all of which have enharmonic parallels in music. Chapels add small geometric figures to the basic circles and polygons to give a great variety of floor plans, in which each geometrical figure retains its clear unity and simple ratios that bind all elements of the plans and elevations into a harmonic unity.
De Re Aedificatoria remained the classic treatise on architecture from the 16th until the 18th century.
