Metoposcopy is a form of divination and character reading based on the lines, wrinkles and marks of the forehead. Developed mainly in Renaissance Europe as a branch of physiognomy, it linked each forehead line to a planet and claimed to reveal temperament and destiny. Its best-known authority was the Italian physician Girolamo Cardano. Today it is regarded as a historical curiosity without scientific basis.

Definition
The term metoposcopy comes from the Greek metopon, "forehead," and skopein, "to look at" or "examine." Practitioners studied the number, length, direction and continuity of the horizontal lines across the forehead, together with moles, scars and other marks, and interpreted them as signs of a person's character, health and future. It belongs to the broader tradition of physiognomy, the attempt to read inner qualities from outward appearance, and to the family of bodily divination that includes palmistry (chiromancy).
History
Physiognomy has ancient roots, and a treatise attributed to Aristotle, the Physiognomonica, was influential in the Middle Ages. Metoposcopy as a distinct discipline, however, took shape in the Renaissance, when learned interest in astrology, natural magic and the correspondences between the human body and the heavens reached a high point.
The figure most associated with it is Girolamo Cardano (1501-1576), the Italian physician, mathematician and astrologer known for his work on algebra and probability. Cardano wrote extensively on the subject, and his collected material was published after his death as Metoposcopia in Paris in 1658, accompanied by several hundred woodcut illustrations of faces with their forehead lines and interpretations. Other 16th- and 17th-century authors also produced manuals, and metoposcopy was often taught alongside chiromancy and astrology in popular fortune-telling books.
The Planetary System
In the most widespread system, the forehead was divided into seven horizontal zones, each governed by one of the seven classical planets. Reading from the top of the forehead downward, the lines were usually assigned to Saturn, Jupiter, Mars, the Sun, Venus, Mercury and the Moon, though authors differed in details. Each line was thought to reflect the influence of its planet on the individual.
- A long, straight and unbroken line was generally considered favorable, indicating the positive qualities of its planet.
- Broken, wavy or crossed lines suggested obstacles, misfortune or weakness in that area of life.
- Moles and marks were interpreted according to their position, much as in astrological charts.
This scheme expressed the Renaissance belief in correspondences between the microcosm, the human being, and the macrocosm, the universe, a belief shared by physicians such as Paracelsus.
How a Reading Was Made
Manuals of metoposcopy advised the reader to examine the forehead in good light, usually with the subject relaxed or lightly frowning so that the lines became visible. The examiner first counted the lines and noted which planetary zones they occupied, then assessed their length, depth, straightness and whether they were broken, forked or joined by smaller lines. Signs were weighed together, and the overall judgment was often combined with the subject's horoscope, complexion and palm.
Interpretations covered temperament, likely illnesses, fortune in marriage and wealth, and sometimes the manner or time of death. Cardano's illustrations paired each pattern of lines with a brief verdict, giving readers a kind of visual dictionary. Like other divinatory systems of the period, the method allowed considerable latitude, so that two readers could reach different conclusions from the same face, a point later critics were quick to note.
Reception and Criticism
Even in its heyday metoposcopy had critics. Some theologians condemned it, together with other forms of divination, as superstitious or as an improper attempt to know the future. As the Scientific Revolution advanced and astrology lost its standing among scholars in the late 17th and 18th centuries, metoposcopy declined into a subject of popular almanacs and fortune-telling manuals.
Modern science finds no evidence that forehead lines predict character or destiny. Forehead wrinkles are shaped by age, facial expression habits, sun exposure and genetics. Historians value metoposcopy as a window onto early modern ideas about the body, the stars and human nature, rather than as a working method.
Related Practices
Metoposcopy sits among many historical methods that sought meaning in visible signs. These include palmistry; the study of facial features in general physiognomy; mirror divination, or catoptromancy; crystal gazing; and more unusual forms such as gyromancy, which relied on walking in a circle until dizzy. Together they illustrate how widely early modern people looked for hidden order in the body and the world.

Frequently asked questions
What is metoposcopy?
Metoposcopy is the practice of reading a person's character and fortune from the lines and marks on their forehead. It developed in Renaissance Europe as a branch of physiognomy and was usually tied to astrology, with each of seven forehead lines associated with one of the classical planets.
Who invented metoposcopy?
No single person invented it, but the Italian physician and mathematician Girolamo Cardano (1501-1576) is its most famous authority. His Metoposcopia, published posthumously in Paris in 1658 with hundreds of illustrations, became the classic reference. Earlier physiognomic traditions going back to antiquity provided its general background.
Is metoposcopy scientifically valid?
No. There is no scientific evidence that forehead lines reveal personality or predict the future. Wrinkles form mainly through aging, repeated facial expressions, sun exposure and genetics. Metoposcopy is studied today as part of the history of divination and early modern ideas about the body and astrology.
