The Well-Heads of Venice – Alberto Rizzi

Motivation

Venice is one of the cities in Europe with the richest and largest number of well-heads, locally known as "vere da pozzo". This term refers to the stone structure surrounding the pipe of a well with protective function. Across history, the role of wells for Venice has always been crucial, in first place to assure drinking water for citizens. Although on water, the city needed wells to store unsalted water. They were placed most of the times in the middle of a square or a private courtyard to collect rainwater and filter it in the ground. In times of drought they were filled with freshwater from the near Brenta river. Over time the uncovered part of these wells, the visible one, started to become more and more relevant also in cultural and artisitc terms. The aim of the project is thus to highlight their significance by classification and 3D modelling. With such an augmentation, we could expect to be able to extract information about their common structures and patterns and also their positioning.

Project Plan

Main steps of the project:

• Preliminary research on the net and books: wells classification.
• Identification of common and particular features.
• Definition of parameters to describe all these traits digitally.
• Creation of one single 3D model capable of describing the larger number of possible wells.
• Starting from this model, replica of the wells in the book "Vere da Pozzo di Venezia" by Alberto Rizzi.
• Wells database (?).
• Wells placing (?).
• Tada!

Methodology

The well-heads of Venice or "vere da pozzo" feature detailed artworks such as stone sculptures. It is challenging to replicate them with a procedural 3D modelling process. The goal is to identify the most basic typologies of wells with basic geometric shapes and use them to model a simple shape of each well with Rhino Grasshopper.

Common typologies of wells:

• Base with circular, square, hexagonal, octagonal, decagonal (10), dodecagonal (12) shapes.
• Top with circular, square, hexagonal, octagonal, decagonal (10), dodecagonal (12) shapes.
• Edges are either sharp or embedding a sculpture that cut them.
• Well-heads rest on a slab with one, two or three steps.
• Top 10-15cm of the well either have flanges with square or circular profiles or arcades

The following illustrations come from the book Vere Da Pozzo Di Venezia, Alberto Rizzi, La Stamperia Di Venezia Editrice, 1981. They illustrate the typologies.

Classification by stylistic appearance and historical period:

Type	Period	Features
Archeological	Greek and Roman	Rough, made from column shafts, altars, memorial stones, cinerary urns and other pieces.
Carolingian	VIII-X centuries	Cubic, decorated with symbols of Christian art
Venetian-Byzantine	XI-XIII centuries	Free-standing cylinder decorated with pillars or columns
Gothic	XIV-XV centuries	Like capitals of columns or pillars, with square frame
Traditional	from 1300	Cylindrical shaft with small arches in the corners
Lombardesque	late XV-early XVI centuries	Modelled like columns capitals
Renaissance	mid XV-mid XVI centuries	Polygonal shape with figures in the lateral boxes
Baroques	XVI-XVIII centuries	Double swelling in the middle
Neoclassical	XVIII-XIX centuries	Very simple cylindrical structure

Set of parameters:

Number of slabs and for each slab:

• Height
• Outer diameter (without mouldings)
• Number of polygonal edges at the top, 0 for circle
• Number of polygonal edges at the bottom, 0 for circle

For the outline of the moulding:

• Starting point position and direction (2D)
• Ending point position and direction (2D)
• Middle point position, direction (2D) and scale factor of the opposite direction
• Shear factor
