"plant which turns its flowers and leaves to the sun," 1620s, from French héliotrope (14c.) and directly from Latin heliotropium, from Greek heliotropion, from helios "sun" (see sol) + tropos "turn" (see trope). The word was applied c.1000-1600 in Latin form to sunflowers and marigolds. Related: Heliotropic.

The heliotrope is an instrument that uses a mirror to reflect sunlight over great distances to mark the positions of participants in a land survey. The heliotrope was invented in 1821 by the German mathematician Carl Friedrich Gauss. The word "heliotrope" is taken from the Greek: helios , meaning "sun", and tropos , meaning "turn". It is a fitting name for an instrument which can be used to "turn" incoming sunlight (via reflection).
Heliotropes were used in surveys from Gauss's survey in Germany in 1821 through the late 1980s, when GPS measurements replaced the use of the heliotrope in long distance surveys. Colonel Sir George Everest introduced the use of heliotropes into the Great Trigonometric Survey in India around 1831, and the US Coast and Geographic Survey used heliotropes to survey the United States. The Indian specification for heliotropes was updated in 1981, and the American military specification for heliotropes (MIL-H-20194E) was retired on 8 December 1995.
Surveyors used the heliotrope as a specialized form of survey target; it was employed during large triangulation surveys where, because of the great distance between stations (usually twenty miles or more), a regular target would be indistinct or invisible. Heliotropes were often used as survey targets at ranges of over 100 miles. In California, in 1878, a heliotrope on Mount Saint Helena was surveyed by B.A. Colonna of the USCGS from Mount Shasta, a distance of 192 miles (309 km).
The heliotrope was limited to use on sunny days and was further limited (in regions of high temperatures) to mornings and afternoons when atmospheric aberration least affected the instrument-man's line of sight. The heliotrope operator was called a "heliotroper" or "flasher" and would sometimes employ a second mirror for communicating with the instrument station through heliography, a signalling system using impulsed reflecting surfaces. The inventor of the heliograph, a similar instrument specialized for signaling, was inspired by observing the use of heliotropes in the survey of India.
Heliotrope most often refers to:
- Heliotrope (color), a pink-purple color, named for the color of the flowering plants (next)
- '' Heliotropium'', a genus of flowering
Heliotrope is a 1920 American silent drama film directed by Charles Maigne and written by Robert W. Chambers and Will M. Ritchey. The film stars Wilfred Lytell, Ben Hendricks Sr., Julia Swayne Gordon, Betty Hilburn, Diana Allen, and Frederick Burton. The film was released on November 28, 1920, by Paramount Pictures.
The mineral aggregate heliotrope (from Greek ἥλιος, hḗlios “Sun”, τρέπειν, trépein “to turn”), also known as bloodstone, is a variety of jasper or chalcedony (which is a cryptocrystalline mixture of quartz). The "classic" bloodstone is green jasper (chalcedony) with red inclusions of hematite.
The red inclusions are supposed to resemble spots of blood; hence the name "bloodstone". The name "heliotrope" derives from various ancient notions about the manner in which the mineral reflects light. These are described, e.g., by Pliny the Elder ( Nat. Hist. 37.165).
Heliotrope was called "stone of Babylon" by Albert the Great (1193–1280) and he referred to several magical properties, which were attributed to it from Late Antiquity. Pliny the Elder (1st century) mentioned first that the magicians used it as a stone of invisibility. Damigeron (4th century) wrote about its property to make rain, solar eclipse and its special virtue in divination and preserving health and youth.
Heliotrope features as a healing stone in one of Boccaccio's stories in the Decameron as well as in a musical comedy derived from it.
Heliotrope is sometimes used in carved signet rings and is the traditional birthstone for March.
The Heliotrope is an environmentally friendly house designed by the German architect Rolf Disch who also designed the Sonnenschiff (Sun Ship). Three such houses exist in Germany, the first experimental version having been built in 1994 as the architect's home in Freiburg im Breisgau, while the other two are used as exhibition buildings for the Hansgrohe company in Offenburg and a dentist's lab in Hilpoltstein in Bavaria. The Heliotrope in Freiburg was the first building in the world to capture more energy than it uses, all of which is entirely renewable, emissions free and CO neutral. The structure physically rotates to track the sun, which allows it to harness the maximum natural sunlight and warmth possible. Several different energy generation modules are used in the building including a dual-axis solar photovoltaic tracking panel, a geothermal heat exchanger, a combined heat and power unit (CHP) and solar-thermal balcony railings to provide heat and warm water. These innovations in combination with the superior insulation of the residence allow the Heliotrope to capture anywhere between four and six times its energy usage depending on the time of year. The Heliotrope is also fitted with a grey-water cleansing system and built-in natural waste composting.
At the same time that Freiburg’s Heliotrope was built, Hansgrohe contracted Rolf Disch Solar Architecture to design and build another Heliotrope to be used as a visitor’s center and showroom in Offenburg, Germany. A third Heliotrope was then contracted and built in Hilpoltstein, Bavaria to be used as a technical dental laboratory. Disch’s unique design accommodates different utilization from private residences to laboratories, and nevertheless maintains the structure’s positive energy balance. In addition to the original Heliotrope design, Rolf Disch has drawn plans for larger versions of the project to be built as a rotating hotel, which gives every guest a beautiful view, as well as administrative buildings and even an exhibition pavilion for the EXPO 2010 in Shanghai.
