Prehistoric abstract symbol used
in Upper Paleolithic cave art
It is referred to as a "Spanish tectiform" only because it is found exclusively in Northern Spain. Please note that its shape is quite different from the regular roof-shaped tectiform sign found in France.
According to Canadian scholar Genevieve von Petzinger, an international authority on geometric symbols created by Ice Age humans, it is one of only 32 abstract signs to be used during the era of Upper Paleolithic art.
Spanish tectiforms were nearly always painted on the walls of caves, usually in red ochre but occasionally in black mananese dioxide. Engravings would only be done on bone or ivory.
These symbols are commonly rectangular in shape. Both the long sides of the rectangle can be curved, while the inside of the rectangle can differ significantly.
Most commonly, it is divided lengthways down the middle into two sections, and then divided shortways into three, thus forming six internal compartments.
However, sometimes it is only divided into three sections, and other times not divided at all.
The internal dividing lines may be left bare, or else embellished in various ways, altering the internal shape accordingly.
In short, "Spanish tectiforms" appear in many different varieties with few standard characteristics.
The origins of this symbol, found in paleolithic art, is anyone's guess. Its shape is too variable and no two examples are the same.
The fact it is seen only in caves in Northern Spain, suggests its origins are local and not imported, and its overall complexity suggests it was developed in stages.
The sign may have started out as a quadrangle, before being elongated and gradually divided into segments, to which more and more intricate details were added over time.
Unlike figurative paintings of (say) rhinos or horses, "Spanish tectiforms" could be painted by almost anyone. That said, there was more to cave painting than simple brushwork.
Sometimes images required careful placement or alignment, to blend with the contours of the rock, or to avoid interfering optically with other paintings. In such cases, the symbols would almost certainly be painted by an artist.

These symbols are only seen in the caves of Northern Spain - notably Cantabria and the Azurias.
See, for instance, the black "Spanish tectiforms" at Altamira Cave, Santillana del Mar, and Las Chimeneas Cave, at Monte Castillo; and the red versions in La Pasiega Cave and El Castillo Cave at Puente Viesgo.
At least one Spanish tectiform is present at La Garma Cave in Cantabria.
They are the most abundant signs in La Pasiega, and make up a specific 'Tectiform Corner' at El Castillo.
Some anthropologists have suggested that these symbols were used as identity markers for certain clans or family groups.
If true, the visual flexibility of the symbol allows plenty of scope to express the structure and membership of the group in graphical terms.
That said, most prehistorian scholars agree that we know almost nothing about the origins, authorship, cultural context or meaning of these signs, and have no real leads to explore, except possibly the habits and customs of modern day hunter-gatherers, surviving in remote jungle areas of South America or SE Asia.
