How are geoglyphs made?
Etymologically, geoglyphs mean engravings or carvings in the earth.
How geoglyphs are created has been the subject of much speculation and debate among archaeologists and researchers. These patterns can be created positively by piling up stones, gravel or earth; they can be created negatively by removing stones, vegetation or soil. Although specific techniques may vary according to location and period, here are a few methods generally considered plausible for creating geoglyphs:
1- Traced on the ground: Some geoglyphs were traced directly on the ground by excavating or moving stones to form patterns. This method requires careful planning and precision in execution to achieve neat shapes and regular lines.
2- Rope systems: Some geoglyphs, particularly those featuring straight lines or geometric patterns, could have been created using systems of taut ropes to maintain equal distances. Builders would have used stakes and precise measurements to ensure the symmetry and alignment of the patterns.
3- Aerial marking techniques: Some geoglyphs are so vast that they can only be fully appreciated from a certain height. Some researchers suggest that aerial marking methods, perhaps using balloons or temporary scaffolding, were employed to guide the creation of the complex patterns.
4- Teamwork: The creation of large-scale geoglyphs would often have required the collaboration of many people. Coordinated teams would have worked together to implement complex designs, perhaps using visual signals or rudimentary communication systems.
5- Astronomical elements: Some geoglyphs are aligned to correspond with astronomical events, such as solstices or equinoxes. This has led to speculation that the builders used astronomical knowledge to precisely orient their creations.
It is important to note that the exact methodology used to create geoglyphs can vary according to culture, time and geographical context. The ongoing study of these mysterious archaeological creations is helping to broaden our understanding of the ingenuity of ancient civilizations. Engraved on the ground, the lines were sometimes too fine to be seen by the naked eye. Today, archaeological sites can be located using satellite imagery.
Geoglyphs - why?
The "why" behind the creation of geoglyphs, particularly the Nazca lines, remains one of archaeology's most intriguing mysteries. Several theories have been put forward, although the lack of direct evidence makes it difficult to confirm any of them. Here are some of the main theories explaining the "why" of geoglyphs:
1- Religious rituals: Some researchers suggest that geoglyphs had a religious or ceremonial significance. The figures depicted may have been worshipped as deities, or the lines may have been used as part of rituals linked to astronomical events.
2- Astronomical calendar: Some geoglyphs are aligned to correspond with astronomical events such as solstices or equinoxes. Some believe that the lines served as astronomical calendars, enabling ancient inhabitants to track the seasons and plan their agricultural activities accordingly.
3- Water resources: Other researchers suggest that the geoglyphs were linked to the search for water resources. Some patterns may have been traced to indicate the presence of underground water sources, playing a role in the survival of populations in these arid regions.
4- Spiritual paths: Some geoglyphs, particularly the straight lines, may have been used as ritual or spiritual paths, travelled during ceremonies or pilgrimages.
5- Artistic expression: A simpler theory suggests that geoglyphs were forms of artistic expression, created for aesthetic, cultural or symbolic reasons. The motifs could have been status symbols, representations of local wildlife or simply works of art created for creative pleasure.
It is important to note that these theories are not mutually exclusive, and it is possible that different lines served different purposes. In the absence of written proof, a precise understanding of the "why" behind geoglyphs remains an enigma that fuels the curiosity of researchers the world over.

Nazca symbols studies
Paul Kosok and Maria Reiche were two important figures associated with the study and preservation of the Nazca lines in Peru. Here's a look at each of these researchers:
Paul Kosok was an American academic and archaeologist, born on November 8, 1899 and died on May 23, 1959.
Major contributions: Paul Kosok is often credited with highlighting the importance of the Nazca lines. In 1939, while flying over the site, he noticed a series of lines that appeared to form geometric patterns and piqued his interest. Later, in collaboration with German archaeologist Maria Reiche, he contributed to the first serious study of the Nazca lines. He also suggested that the lines could be linked to astronomical phenomena.
Maria Reiche was a German mathematician and archaeologist, born on May 15, 1903 and died on June 8, 1998.
Major contributions: Maria Reiche is often referred to as the "Lady of the Nazca Lines". After Paul Kosok's death, she continued his work and devoted much of her life to the study, preservation and promotion of the Nazca lines. She made detailed measurements, mapped the lines, and defended the theory that the lines were linked to astronomical calendars. She was also instrumental in raising awareness of the site's preservation and recognition as a UNESCO World Heritage Site.
These two researchers played a crucial role in highlighting the importance of the Nazca lines and opening up new perspectives for understanding these mysterious creations. Maria Reiche, in particular, has left a lasting legacy as a passionate guardian of the site and as a scientist who has devoted much of her life to its study and preservation.
Who drew the Nazca lines?
The enigma of the Nazca Lines, also known as Nazca geoglyphs, has persisted for decades, and the exact identity of the people who drew them remains unknown. The Nazca Lines are a group of pre-Inca geoglyphs located in the Nazca desert in southern Peru. The lines, which include geometric figures, stylized animals and other motifs, stretch for kilometers and are only clearly visible from a certain height.
The Nazca geoglyphs were created by the Nazca civilization, a pre-Incaic culture that flourished in the region between around 200 BC J.-C. and 600 AD. J.-C. However, despite the attribution of the Nazca lines to the Nazca people due to chronology, the question of why these lines were created and how they were drawn with such precision remains largely unanswered.
The exact techniques used to draw the Nazca lines remain a mystery. Hypotheses range from the use of simple ropes and stakes to more complex methods involving astronomical instruments or advanced knowledge of geometry.
Although the Nazca civilization is often associated with the lines, it is important to note that other pre-Inca cultures in the region may also have contributed to the creation of certain geoglyphs. The Nazca lines remain an active subject of research, and new discoveries and interpretations are emerging as scientists continue to study these mysterious relics of the past.
Examples of geoglyphs: from condor to monkey
Geoglyphs at Nasca include an impressive variety of motifs, from simple geometric figures to complex representations of animals and abstract forms. Here are some notable examples of geoglyphs at Nasca:
The condor: An impressive figure depicting a condor, an emblematic bird of the Andes, with broad, outstretched wings. The Condor is a large motif, measuring around 134 metres in length. Like many other Nazca geoglyphs, it is designed to be fully appreciated when viewed from a certain height.
The Hummingbird: A geoglyph depicting a hummingbird, a finely detailed bird with outstretched wings. It measures around 50 meters in length.
