Genesa and Pentasfera: History, Sacred Geometry and My Dowsing Observations

Genesa and Pentasfera are now familiar objects to those who move in the world of radionics, radiesthesia and sacred geometry. Yet behind their fascinating aesthetics there is a precise history — and, in my view, a certain misunderstanding worth clarifying with some documentation at hand.

Origins: Derald Langham and Circle Gardening

Derald George Langham, agricultural geneticist and founder of the Genesa Foundation
Derald George Langham (1913–1991), American geneticist and agronomist. He worked in Venezuela for over twenty years, contributing to the genetic selection of sesame, maize and beans in the tropical lowlands.

The Genesa was born not as an esoteric tool but as the discovery of an agricultural geneticist. Derald George Langham (1913–1991), an American, trained in genetics at Cornell University and from 1947 worked in Venezuela, collaborating for many years with the Instituto Agrario Nacional and with research programmes supported by the Rockefeller Foundation. His main task was to improve sesame varieties grown in the Venezuelan lowlands — an unheralded but practically significant work that would lead to him being remembered as the «father of sesame» in the western hemisphere, alongside important contributions to maize and beans.

The problem Langham faced in his own experiments was at once mundane and frustrating: during the intense tropical rains typical of the wet Venezuelan months, the different genetic lines of sesame he was selecting tended to cross-pollinate involuntarily, contaminating the trials and rendering months of selection work useless. The solution he found was to arrange each variety in circular plots rather than the usual rectangular rows, using the space between circles as a natural buffer zone.

Cover of Circle Gardening by Derald Langham
The cover of Circle Gardening (1978), the book in which Langham presented his circular cultivation method, his harvest observations and his early reflections on the geometry of the Genesa.

Something unexpected happened: plants grown in the circles grew better. Not marginally — the difference was visible and measurable. Plants on the outer edges of the circles turned out taller, more robust, with greater seed production. Insect infestations fell dramatically. In some comparative experiments with rectangular control plots, the harvests doubled.

Langham did not simply note the anomaly: he tried to understand it. He repeated the trials on maize and beans, obtaining similar results. He described the effect systematically in Circle Gardening (1978), which documents the variations of the method — single circles, concentric circles, multiple-circle compositions — and the results obtained on different tropical crops. The basic principle that emerged from his observations was that circular geometry created something he called a «growth field»: an influence on the cultivated environment not reducible to conventional agronomic factors such as irrigation, soil fertility or seed variety.

What produced this effect remained an open question for him. Langham himself did not commit to a definitive explanation: he observed, documented and continued gathering data. Over the years he obtained reproducible results in different conditions, which convinced him increasingly that the effect was real and linked to geometry itself, independent of soil type or cultivated species.

From Circle Gardening to the Genesa Crystal

If Circle Gardening worked with flat two-dimensional circles traced on the ground, Langham began to wonder what might happen with a three-dimensional structure capable of expressing the same circular geometry in all planes of space simultaneously. As an agronomist who had studied plant embryology, he was familiar with the spherical symmetry of the early stages of cell division — the eight-cell sphere, the morula, the blastula — and noticed a formal correspondence between that geometry and the structure he was developing.

The solution took shape as four equal large circles interlaced so that each is perpendicular to the other three, and all pass through a single common point at the centre. This configuration spontaneously generates a structure that mathematicians call a cuboctahedron — or, in the terminology of Buckminster Fuller that Langham knew well, a vector equilibrium — composed of six squares and eight equilateral triangles. It is the geometry of the densest spherical packing: the figure in which all distances from the centre to the vertices and edge midpoints are equal, and which Fuller described as the geometric form of maximum balance in space.

Langham called this form Genesa, combining «gene» — the fundamental unit of biological information — and «SA», the acronym of the South American continent where he had conducted his research. He first built large versions — wire frames several metres in diameter — and placed them at the centre of experimental fields, seeking to replicate in three-dimensional form the effects already observed with two-dimensional Circle Gardening. The results he reported were consistent with previous observations: improved growth in surrounding crops, reduction in harmful insects, qualitative improvement in harvests.

He subsequently developed smaller table-top versions — the Genesa Crystal — presenting them as symbolic geometry objects with their own energy field, derived directly from the agricultural principle he had observed in the fields. He founded the Genesa Foundation, gave lectures in South America, North America and Europe, and went on to describe the Genesa as a symbolic synthesis not only of cell division stages but of the geometric principle governing life at its most fundamental levels. He remained active until his death in 1991 in Yuma, Arizona.

Genesa Crystal, the three-dimensional frame with four interlaced circles
The Genesa Crystal in its table-top version: four interlaced metal circles generating the cuboctahedron geometry. It derives directly from the large agricultural frames Langham placed at the centre of experimental fields.

A point worth restating clearly: the original use — the heart of Langham’s discovery — was agricultural. The large metal frames in the Venezuelan sesame, maize and bean fields were the primary tool; the small table-top Genesa Crystal came later, as a symbolic derivation and an attempt to bring into domestic form a principle that had proven to work in open fields. This distinction is not secondary: it helps to read the subsequent literature with a more critical eye, which sometimes reversed the priorities, treating agricultural use as a curious application of an essentially «energetic» tool, when in fact the opposite is true.

From Genesa to Pentasfera: A (Mainly) Italian Evolution

The Pentasfera is a more recent derivation of the Genesa: where the latter uses four circles, the Pentasfera uses six, generating an even more articulated geometry with a greater number of intersections and faces. Over time, bases of different shapes — triangle, square, pentagon — were added to the original structure, each loaded with its own symbolic meaning in the more recent literature.

Something I have been able to verify personally, by comparing notes with colleagues and researchers in different countries, is that the spread of these objects is extraordinarily concentrated in Italy. In France practically no one knows them; in Switzerland they are not used; I have found no trace of comparable use elsewhere in Europe. It is, in short, a phenomenon that has taken root and multiplied above all in our country, probably aided by extensive publishing and popular literature that over the last twenty years has accompanied the object.

Crystals, Notes and «Activations»: What the Literature Says

Around the Pentasfera a rather rich literature has grown up over the years, suggesting placing crystals inside it to «charge» them, writing a note with an intention, and performing an activation ritual at the time of purchase, accompanied by a kind of prayer.

Intention note placed inside a Pentasfera
An intention note placed inside a Pentasfera: a very widespread practice in Italy, which merits direct radiesthetic verification before being accepted as effective.

Personally I did this too, years ago, before beginning to study the object seriously. But the more I delved into the question, the more I asked myself a simple question: what relationship exists between these rituals and the use for which the Genesa was originally conceived? Forms, especially sacred ones, undeniably produce shape waves — this is something radiesthesia knows well. But from here to a specific function of «amplifying intentions» through crystals or notes, the step is not automatic, and I wanted to verify it directly.

My Measurements: The Shape Waves of Genesa and Pentasfera

To answer this question I set about measuring, with a pendulum, what Genesa and Pentasfera actually produce. I shared these results at a conference on Biosignatures, accompanied by a summary diagram (reproduced below).

Before getting into the results, two terminological premises somewhat more extended than usual, since they are the language in which the measurements are expressed.

Negative Green: Origins and Structure

Shape waves are the subject of a branch of radiesthesia born in France in the 1930s through the research of physicists Léon Chaumery and André de Bélizal. The two began their investigations observing the Great Pyramid of Cheops and its anomalous radiation, then extended the inquiry to the geometry of simpler solids: wooden spheres, cones, tori. They found that every form emits a field of subtle radiation depending exclusively on its geometry, regardless of the material it is made from. They published their research in Essai de Radiesthésie Vibratoire (1940) and Physique Micro-Vibratoire et Forces Invisibles (1943).

Among the shape waves they identified, the best known and most studied is negative green (V-), patented in 1936. Negative green is the characteristic emission of spherical forms and those close to them, such as the Genesa. It manifests in two distinct, mutually perpendicular components:

  • The electric component, oriented vertically, detectable with instruments calibrated for vertical shape waves.
  • The magnetic component, oriented horizontally, detectable with instruments calibrated for horizontal shape waves.

These two components are not found in the same point simultaneously: they alternate depending on position relative to the form. This is an alternation analogous to the electromagnetic field around a conductor — hence the term «electromagnetic negative green». Chaumery and de Bélizal considered pure negative green potentially destabilising if prolonged: the Great Pyramid itself, with its precise orientation, emits negative green very intensely, which would explain why many sensitives describe it as a powerful but not necessarily comfortable place for extended stays.

BG3: Balance as a Quality

BG3 belongs to a more recent system, BioGeometry, founded in the 1970s by Egyptian architect Ibrahim Karim after encountering the work of Chaumery and de Bélizal. His main innovation was identifying an energetic quality of balance — he called it BG3 — characterised by the simultaneous presence of three components: Gold (O+), Ultraviolet (UV) and Horizontal Negative Green (V-H).

These three components together, unlike each one taken separately, produce an effect Karim describes as centring, harmonising and beneficial for living organisms. He found it in the domes of Romanesque churches, in the carved stones of Egyptian temples, at landscape power points such as sacred springs and telluric grid nodes. In his applied BioGeometry work he documented how it can be evoked through specifically calibrated geometric forms — and it is this quality that appears on the surface of the Genesa. I have discussed it more fully in the article on Biogeometry and Shape Waves.

The Measurement Procedure

I carried out measurements across multiple sessions on two specimens: a medium-sized Pentasfera and a Genesa Crystal approximately 23 cm in diameter. I used three distinct instruments:

  • A standard universal pendulum (Egyptian type).
  • The vertical BioGeometry pendulum, calibrated for the electric/vertical component of shape waves.
  • The horizontal BioGeometry pendulum, calibrated for the magnetic/horizontal component.

The procedure was to approach progressively from the outside inward, recording responses at successive distances: 50 cm, 30 cm, 20 cm, 10 cm, on the metal surface of the circles, and finally at the centre of the structure. The measurements were replicated across multiple sessions weeks apart, and the results remained consistent over time.

Results Zone by Zone

At 20 cm and beyond: no detectable signal with the instruments used. The object produces no perceptible effect at this distance; placing a Genesa Crystal on the opposite side of the room yields no measurable field.

Between 20 cm and the surface: the universal pendulum registers negative green. Separating the components with the specific pendulums: the electric (vertical) component dominates on the sides of the object; the magnetic (horizontal) component dominates above and below. This is the typical alternation of electromagnetic negative green, analogous to that observable around any spherical form.

On the surface of the structure (±5 cm): the signal changes quality distinctly. The universal pendulum orients towards a resonance corresponding to BG3. This applies both on the metal surface of the circles, at the intersection points, and in the space immediately adjacent to the structural rods. It is in this narrow band — a few centimetres wide — that the most interesting energy quality of the Genesa is concentrated.

Inside the structure: electromagnetic negative green returns — the same quality detected when approaching from outside. This is not an «empty» or neutral field: it is an active field, but its quality is that of negative green, not BG3.

What This Means for Notes and Crystals

From this picture one can draw an important practical conclusion: a crystal, an intention note or any other object placed at the centre of the Genesa is immersed in electromagnetic negative green. Not in BG3 — which is found exclusively on the metal surface of the structure, in a band of a few centimetres. The Genesa does not amplify written intentions, nor does it «charge» crystals with a special harmonising quality: it exposes them to a shape radiation that has its own characteristics, but not those that the popular literature tends to attribute to it.

This does not mean the note practice does not work — but if it works, it works by virtue of the intention itself, not the geometry containing it. As I often say: intention works just as well inside a shoe. It naturally remains an invitation to verify for oneself: the results I obtained were consistent over time, but every practitioner is encouraged to repeat the measurement with their own instruments and draw their own conclusions.

A note on dimensions: all measurements refer to my personal specimens of approximately 23 cm in diameter. It is plausible that larger objects produce different intensities and ranges — both outward and inward — an aspect that would merit systematic investigation.

A Curious Observation: The Candle Flame

A small experiment, which I have seen proposed online and personally verified: placing a lit candle inside a Genesa or Pentasfera, the flame — normally unstable and flickering in the open air — tends to remain still. This is an effect that probably also lends itself to a more ordinary physical explanation (the structure itself modifies air flows), but it remains a small visible sign, as well as being simply a very beautiful object to observe. As for plants, the empirical observation — mine and that of many other practitioners — is that they benefit when positioned nearby, in continuity with Langham’s original agricultural use, which is, after all, exactly where it all began.

Sacred Does Not Automatically Mean Beneficial

There is one point I always insist on when talking about sacred geometry: the sacredness of a form does not automatically imply a positive effect on those who frequent it. Sacred forms produce shape waves — this is a fact — but the quality of that energy must always be verified, not presumed.

An example I often cite: measuring with the Archangel pendulum the Abbaye du Mont Saint-Michel in France — one of the best-known sacred places in Europe — I obtained a reading of electric red. Not exactly an indication of a place where one would feel at ease spending the night. It is a reminder to maintain, even in the presence of objects and places with strong symbolic value, an analytical approach: one measures, verifies, and only then draws a conclusion.

In Summary

Genesa and Pentasfera remain for me fascinating tools, aesthetically perfect and rooted in a real history — that of a geneticist who, observing his Venezuelan sesame fields, discovered that circular geometry interacted with plant life in a measurable and reproducible way, and from there developed a three-dimensional form capable of expressing that same principle in space. The more recent literature has added meanings and rituals that, in my view, should be taken with appropriate critical distance, while direct measurements remain the most reliable tool for truly understanding what these objects produce, inside and around themselves.
