Section
3 - Case Studies: Anatomy seen through the lens of architectural drafting
Figure 1 – Leonardo da Vinci, Heroic Nudes (anatomy
and static and dynamic equilibrium) and a battle scene, 1503-6, Red chalk and
pen and ink, 16 x 15.3 cm, Windsor Castle, Royal Collection Trust
(Image taken from web).
In a
drawing from 1503-6 titled Heroic Nudes
(anatomy and static and dynamic equilibrium) and a battle scene (fig. 1), da
Vinci shows a standing figure and the inside view of a leg with a plumb line
drawn from the front of the pelvis to the toes. In the full figure, a center of
balance is also indicated by showing a vertical plumb line drawn through the
central axis of the hip (roughly over the great trochanter of the femur).
Should the figure move off of this line either forward or backward, it is
assumed that movement would occur. Important here is the idea that da Vinci is
studying dynamics, or thinking the potential of transformative qualities, and
not simply depicting a static position. This analysis of weight gives insight
to da Vinci's interest in anatomy as a tool for critical thinking regarding the
structure, composition, and balance of the figure and its component parts (and
not that of shading/studying only the external/phenomenal qualities). For da
Vinci, the human body is governed by geometric rules branching to all systems
(vessels, lungs, muscles, etc.), all of which have dynamic/animated force. By
thinking more predominantly of the dynamic weight and balance created between
the parts of the figure, we are able to make a cursory comparison to the
analytical thinking required in the critical act of organizing weight in
building, and understanding the problems inherent within.
Figure 2 - Leonardo da Vinci, The human cranium sectioned,
1489, Windsor Castle, Royal Collection Trust
(Image taken from web).
To
push this idea further, in da Vinci's drawing The human cranium sectioned (fig. 2), a three-quarter, top view of a skull is shown with the inside of
the cranium visible. In this study of the skull, we can see da Vinci using
methods of perspective as crucial tools in representing the “cut away” view. Da
Vinci shows the cranial mass sectioned with the outermost quarter removed, exposing
the interior.
Figure 3 - Studies of the Leg, c. 1485-90, Pen and
ink over metalpoint, on pale blue prepared paper, 22.2 x 29.0 cm
, Royal Collection Trust (Image taken from web)
A similar method is used in his Studies of the leg (fig.3),
showing the lateral view of a right leg. Of specific interest in this study is the
sectioned pieces separated to show the varying widths of the leg. One area
(mid-thigh) is then moved to the side to show the thickness of the varied
muscle groups contained within. Notice here the top-down view of the leg, and
the way it resembles an elevation or floor plan. While these first two examples
do not show an exact architectural crossover, they do show a willingness to
treat the figure in the exact same way, using the same tools of representation
(perspective, changing angles, consideration of inside and outside space).
Before
moving to a discussion of the more anthropomorphic examples of anatomy and
architecture, I would like to introduce one more artist essential to the discussion
of visualizing proportions, anatomy, and the architectural design of the figure
during the Renaissance: Albrecht Dürer.
Albrecht
Dürer
Albrecht
Dürer, a German artist working in Northern Europe, was greatly influenced by Leonardo
Da Vinci as well by the writings of Vitruvius. Dürer makes this
connection clear, stating:
As
regards any discussion on building, or of its elements, I believe none among
our eminent capimaestri or artisans
have overlooked how the ancient Roman author Vitruvius wrote so splendidly in
his books regarding the decoration of architecture: his example is a lesson to
us all.[1]
Dürer’s text on the
proportions of the figure was published in 1528. Prior to this, he authored books
on the applications of geometry and a treatise on fortifications. Dürer ‘s motivations
in studying a wide range of body types, genders, and varying shapes and sizes
of individual parts was an attempt to prove that art was founded on a
determinate set of rules. To this point, and still building off the thoughts of
Vitruvius, Dürer states:
That
master of the ancient world Vitruvius, architect of the grandiose building in
Rome, states that he who intends to build should conform to human beauty,
because the body conceals the arcane secrets of proportion. Hence, before
discussing buildings, I intend to explain the form of a well-built man, and
then a woman, a child, and a horse. In this way you will acquire an approximate
measure of all things about you.[2]
The key term in Dürer’s
comment is "well-built man." Following in Vitruvius's footsteps, Dürer regards man as architectural form. While Dürer wasn’t as concerned with
the interior anatomy and dissection as da Vinci, his thinking shows a complete
geometric and projective system for the representation of the human body. Dürer
also provides an incredible range of perspective positions and views.
Figure 4 - Albrecht
Durer, Stereometric Man; thirteen
cross-sections of the body, c. 1523, pen and ink, 11.5 x 8 in., Nuremberg,
Germany, National Museum (image taken from web).
Specifically,
Dürer’s Stereometric man with thirteen
cross-sections of the body (fig. 4) shows a figure built entirely from
planar cubes and or boxes. With the figure holding its weight on the right leg,
a clear contrapposto position is
held. Surrounding the figure within the margins and surrounding space are
thirteen different elevation plans/views of the figure taken from top to
bottom. This ground plan or project of the figure cut at various moments shows
the body as if it were a blueprint with the same technical vocabulary as the
architect.
Figure 5 – Albrecht
Durer, Stereometric man, front view,
profile and ground plan, c. 1519, pen and ink, 11.5 x 8.5 in.
An additional example titled Stereometric
man with front view, profile and ground plan (fig. 5) dissolves the figure
even further in architectural abstraction, leaving it only legible as an abstracted
mannequin. Where da Vinci, in the initial drawings discussed, begins to view
anatomical parts and pieces through the lens of geometric perspective (with a
nod to architectural techniques), Dürer goes beyond to understand the
figure as a pure subject of architecture, presenting the body, in total, as a
geometric assemblage.
In
the above examples, Dürer shows the figure as a series of “ground plan” views
as well as a coordinated set of parallel projections and cross sections,
presenting an interpretation of the figure as something constructed with
mechanical instruments in strict planar terms. In these cases, Dürer’s figures
shrink from having human detail so entirely that they essentially dissolve into
some hybrid form of human structures. While
lacking some of the eloquence in design and realization that da Vinci's
sketches clearly possess, Dürer still provides an example of this shared form
language that is also used by Leonardo da Vinci.
Section
3 – Mental Sculpture: Case studies in the plastic molding of geometries from
the figure to architecture, or instances where abstraction gives way to the
figure blending into architectural motifs.
With
the above in mind, I will end with a few more examples that show a more developed
design at work illustrating the transformative language shared between anatomy and
architecture. In building to this point, my goal has been to establish a
foundation (both in philosophy, process, and practice) for the potential for
anatomy to be seen as synced to that of an architectural tradition. With that
foundation in mind, I will isolate more
anthropomorphic examples that express more clearly this dissolve or blend
between the two.
Figure 6 Leonardo da Vinci
In fig. 6, Leonardo da Vinci shows a dissection of the
skull, neck, and throat paired alongside plans for columns. It appears that in
this image, da Vinci has used the proportions of the hyoid bone, throat, and surrounding
cartilage as a departure point for the columns shown to the right. Should this indeed
be the case, we can examine this as a consideration of the macro idea of
proportion and harmony aimed at a very small/micro design hidden within the
surface contours of the neck. While this image very clearly shows a shared thought
existing between the two, it also alludes to the transformative aspects and
potential mental sculpting which may be taking place, as the mass and
proportion of the throat gradually resolves into the solid cylindrical mass of
the column on the right.
Figure 7 – Leonardo
da Vinci, The muscles of the shoulder and
arm, and the bones of the foot, c.1510-11,
pen and ink with wash, over black chalk, 28.9x20.1 cm, Royal Collection Trust (image
taken from web)
In
the same spirit as above, Anatomical
studies of the shoulder region (fig. 7) shows da Vinci's extremely elegant
and concise anatomical drawings/dissection of the arms, shoulder, as well as
the bones of the foot. My specific interest here is in the top of the arms
pictured in the center of the image showing the external anatomy (deltoid)
removed. Da Vinci here has focused on the intricate structure of tendons and
muscles connecting the rib cage/scapula into the top of the humerus.
Surprisingly, this extremely complicated transition isn’t at all busy or
convoluted in appearance. Rather, a very clear and orderly progression of
rounded triangular and square shapes design a progression of negative shapes
between the connecting muscles.
Figure 8 – Leonardo
da Vinci, Studies for the tiburio of
Milan Cathedra, c. 1487, ink, 28.2x23.7 cm, Codex Atlanticus, Biblioteca
Ambrosiana, folio 851, Milan, Italy.
When
compared to the accompanying sketch Studies
for the tiburio of Milan Cathedral (fig. 8), there appears to be a great
deal of formal similarity. Here da Vinci is studying, or perhaps searching for,
a solution to the tiburio, or crossing tower, of the cathedral at Milan. If flipped,
the previous sketch would match perfectly in shape. The tiburio study shows a
very similar shape and design, and leads one to imagine that the shoulder has
been abstracted into a usable language of form/function.
Fig. 9 Leonardo da
Vinci, Studies for lantern of cathedral,
1478-90, red and sepia ink, The Codex Trivulzianus, folio 22, page 41. (Image
taken from web)
Lastly,
in Studies for lantern of cathedral (fig. 9), da Vinci shows what looks to be a simplified design for a rib cage in the
top right corner of the image. The flat dome or egg shape is shown with a line
down the middle and an opening at the bottom. Looking at this shape with an eye
towards anatomical dissections, we could easily understand this as an exact
diagram for the rib cage - the line down the center being the sternum, and the
opening at the bottom being the thoracic arch (or separation at the tenth rib).
The fascinating aspect to this image is the almost animated way in which this
form moves from the top right, down, and into the bottom left. As this rib cage
shape moves from the top right down, it begins to take on a more dimensional
appearance, becoming more volumetric. It is almost as if we can see da Vinci's
mental sculpting in process, as the mass of the rib cage slowly transforms into
the top of the Milan cathedral. The volumes shown moving down from the top
right (second and third drawing shown from beneath) appear to have a consistent
geometric volume to that of the rib cage. As it moves further, what once
appears to have been a rib cage, takes place at the top of a centrally planned
cathedral as its dome. Around the margins of this drawing are variations of
this shape showing potential iterations as options. If this is in fact an
accurate description of what is happening within da Vinci's sketch, then we are
able to see a completely fluid practice of anatomy becoming architecture
or vice versa. While this will end my survey of da Vinci's work and thought, I will continue in the next (and last post) with two examples from Michelangelo. While my intention has
not been to relate all of the above ideas directly to da Vinci alone, he does
stand as an exemplary example of this practice, creating a clear model through
which a number of artists might be more easily studied.
