When and how do the Nazca geoglyphs originate?
The geoglyphs originated to the greater part by removing, to a smaller part by heaping of the stones lying on the surface. Apart from a few excavations finds from stone heaps they are hitherto only datable by sherds of pots which broke there or were offered.
As long as other datings lack to a large extent, stylistic attributes of potsherds found there are used instead. To this end it is important to recognize if the sherds came onto the bottom before or after the construction of the geoglyphs.
By more or less intensive clearing of stones more or less well recognizable lines appeared.
A faintly recognizable margin wall (marked) of an prior area is intersected by the margin wall of a later area.
Lines may be as narrow as this (with M. Reiche).
(in Europe:)
men
spirals etc.
one line animals
lines
zigzag
narrow trapezoids
narrow rectangles
broad areas
The dating of the geoglyphs kann only estimated very coarsely taking in consideration the few sure dates and sequences.
In these composite trapezoids, the stones were as well cleared as heaped to walls and rims.
At one or both ends of bigger trapezoids and rectangles there are often platform-like stone heaps where offings tool place. Posts, shells and food was found.
During the excavation of two ‘stone heap altars’ at the end of a trapezoid the stump of a wooden post was found, part of the altar complex.
A presumptive use of ranging poles during the construction of the geoglyphs made it possible to lead them lineally over elevations and hills.
During the unfinished rebuilding, the stones were compiled to rows of single heaps here instead to margin walls.
Here, clearing of the areas (marked) was never accomplished.
