The Human Aura: A. Marques's 1896 Book and Its Meaning

In The Human Aura: A Study, A. Marques describes a person as extending beyond the visible body. His 1896 book presents layers of vitality, emotion, mind and spirit, which he believes clairvoyants can perceive as light, colour and movement. The aura is his way of making a complicated model of human nature visible.
It is not simply a book about matching colours to moods. Marques tries to connect the parts of a person with the wider universe, and to explain why thought and feeling might leave an outward trace. That ambition makes it a revealing document of nineteenth-century Theosophy.
Reading it today calls for two kinds of attention: understanding what the author meant, and asking what supports his claims. Keeping those questions separate lets us explore the book without treating its diagrams as established anatomy or its healing claims as medical advice.
Who was A. Marques, and why did he write this book?
The title page identifies A. Marques as president of the Aloha Branch of the Theosophical Society and credits assistance from M. McElroy. It gives San Francisco's Office of Mercury as the publisher. Those details place the work within an organized spiritual movement, not an anonymous tradition of ancient teachings.
Scholar Jeremy Stolow identifies the author more fully as Auguste Jean Baptiste Marques in his discussion for the MIT Press Reader. Stolow considers Marques's illustration within the history of picturing auras. That is a study of how an idea has been represented, rather than confirmation of the subtle layers Marques describes.
Marques himself gives a modest account of the book's beginnings. His author's preface says it started as a requested lecture for Theosophists in Honolulu and San Francisco. He explains that publication was hurried and invites criticism of the substance. He hopes another writer will complete the investigation.
The other preface, by Marie A. Walsh, is much more confident. She presents his observations as carefully tested and looks toward applications in healing. The contrast is worth noticing: even before the main argument begins, the reader encounters different levels of certainty about the same work.
This is a useful habit when reading old books. A supportive preface may promise more than the author establishes. It belongs to the book's reception and presentation, but it should not replace a close look at the argument itself.
What does “aura” mean in Marques's system?
For Marques, an aura is not one simple halo. It is a collective appearance produced by several aspects of a living being. His descriptions move between bodily emanations, desire, mental activity and spiritual principles. These parts may overlap, so the apparent cloud around a person is not always easy to divide.
The model depends on Theosophy's distinction between the visible body and less visible vehicles of life and consciousness. A vehicle, or sheath, is something through which a principle is said to work. Think of the terminology as the author's map: it tells us how he organizes experience, not what a medical scan would reveal.
Our guide to Theosophy introduces that background. Readers of Blavatsky's The Key to Theosophy will recognize some terms, but the classifications should not be assumed identical. Marques rearranges and subdivides familiar principles to fit the account he wants to give.
He also reaches beyond people. The appendix discusses plants and magnets, suggesting that the aura belongs to a much larger field of relationships. The human figure is the centre of his study, but he does not believe it is an isolated object standing apart from nature.
That wider ambition helps explain the book's appeal. It offers a picture in which bodily life, emotion and spiritual meaning belong to one connected world. The appeal of that picture and the evidence for its literal existence remain different questions.
The layers: a reading map, not a medical chart
The descriptive chapter organizes its material into material, psychic or soul, and spiritual portions. Within those broad groups, Marques makes further distinctions. The terminology can initially feel overwhelming because words from several traditions appear beside the language of electricity, magnetism and heat.
This simplified table helps locate the main ideas without pretending to reproduce every subdivision:
| Part of the discussion | Terms a reader will encounter | What Marques is trying to explain |
|---|---|---|
| Bodily life and its surroundings | Etheric double, Prana, caloric and electric or health auras | How the visible body relates to vitality and claimed emanations |
| Desire and personal mental life | Kama, Kamic sheath, lower Manas | Feelings, passions and the mind connected with personality |
| Higher mental and spiritual life | Higher Manas, Buddhi, Atma, Auric Egg | The less personal and more enduring aspects of his spiritual model |
The distinction between lower and higher mind does not mean one person literally has two brains. It belongs to a philosophy of personal and spiritual identity. Likewise, the Auric Egg is a name for an encompassing spiritual vehicle in his scheme, not a discovered organ.
Marques's discussion of bodily heat illustrates why careful separation matters. Bodies do produce heat. But that familiar fact does not establish all the additional colours, sheaths and clairvoyant readings he attaches to bodily life. A sound starting point can be followed by a much less secure inference.
The same care applies to the phrase “health aura.” Marques connects the appearance of radiating lines with illness and vitality. Those descriptions should not be used to diagnose disease, assess another person's health or decide whether someone needs treatment.
How to read the diagrams
The frontispiece places a human silhouette inside several surrounding layers. It gives the reader a way to hold the system in mind. Instead of following a long chain of unfamiliar nouns, we can see the author's relationships arranged around a recognizable body.
That is what a diagram does particularly well: it makes a theory seem orderly. But order on the page is not the same as verification. A neatly labelled picture can communicate an idea accurately even when the existence of the pictured objects remains unproved.
The book's illustration list also includes Tatwic forms, changes at half-hour intervals, an ear and hand, thought-forms, leaves and a horseshoe magnet. These are not interchangeable kinds of image. Some explain correspondences; others represent appearances the writer says were perceived.
Consider the plant examples. A drawing labelled as the aura of a violet leaf tells us what the observers believed they were seeing around that leaf. It does not, merely by being printed, show that a second observer without that theoretical framework would find the same structure.
The surviving frontispiece in the HIPS edition is a small historical composite. Some fine labels are not fully legible. It is retained as evidence of the original presentation, not replaced by a crisp invented reconstruction that might falsely suggest missing details are known.
For a useful first reading, pair each illustration with its adjoining passage. Ask what is being claimed, who is said to perceive it, and whether the picture is an observation report, a conceptual arrangement or an analogy. The answer may differ from one image to the next.
Why the book sounds both spiritual and scientific
Marques writes as someone who believes investigation will bring Theosophical teachings and science closer together. His introduction invokes reports of photography, experiments and sensitive observers. The language asks the reader to see the aura as something awaiting recognition, rather than a purely poetic image.
Yet a claim that a photograph proves an aura needs more than a printed report. We would need to know how the image was produced, what ordinary effects were excluded, and whether the result could be independently repeated. The book's confidence does not supply all those answers.
Agreement with an existing spiritual teaching creates another problem. If an observer reports exactly the layers that a doctrine predicts, that may look persuasive to a believer. But agreement alone cannot tell us whether the theory guided the observation. Independent testing has to address that possibility rather than assume it away.
This is not a reason to ignore the book. It is a reason to read its evidence as carefully as its conclusions. Marques gives us a close view of a writer trying to place unseen human life inside the investigative language of his period.
It also helps to distinguish analogy from demonstration. A magnet's ordinary effects may make an invisible influence easier to imagine. They do not demonstrate that a person has the particular spiritual envelopes described in the book. The analogy makes an idea accessible; it does not finish the argument.
The Human Aura and Thought-Forms: related, but different
Marques published his study in 1896. Annie Besant and C. W. Leadbeater's Thought-Forms first appeared in 1901. Both works belong to a Theosophical effort to describe less visible aspects of human life, but they give different parts of that effort centre stage.
Marques concentrates on the person and the surrounding layers. Besant and Leadbeater focus on forms said to arise from particular thoughts and feelings. One asks how the human being is constituted; the other asks what thinking and emotion supposedly produce.
The difference resembles a map of a landscape compared with a series of weather pictures. This is a modern reading analogy, not either author's terminology. It helps distinguish a relatively encompassing account from representations of changing events within and around it.
Both books use colour, but that does not make them a single universal colour dictionary. Their terms must be read in context. Our guide to Thought-Forms' colours and illustrations follows that second book's own examples rather than importing meanings from contemporary aura charts.
Readers interested in the broader Theosophical picture can then turn to The Secret Doctrine. It provides a different scale of argument about the universe and humanity, not a laboratory validation of either illustrated study.
What can a modern reader take from the book?
The safest starting point is historical curiosity. What did Marques believe a person was? Why did invisible layers seem a plausible explanation to him? How did a diagram, a witness's report and the vocabulary of scientific investigation reinforce one another?
Those questions make the book useful without converting it into a health manual. Its appendix includes material on developing psychic sight, and its conclusion anticipates healing applications. This article does not recommend those exercises or endorse its claims of protection from disease.
Another valuable question concerns interpretation: how much of what the writer calls seeing depends on already knowing the names and categories? The diagram is easier to understand once we learn the system. That helpful clarity should also prompt us to examine how a system shapes expectations.
The HIPS Books reader's edition of The Human Aura preserves the historical wording, notes, appendix and illustrations. Separately marked vocabulary help and reader guides support the reading; they are not parts of Marques's original argument. Our editorial method explains that distinction.
The book is most rewarding when it is allowed to remain a particular work from 1896. It shows one writer trying to make the unseen person intelligible. We can study the ambition, the images and the reasoning closely without mistaking his confidence for scientific proof.
