History and context
At La Venta, pavements of serpentine blocks were laid out forming geometric designs or schematic faces. After placing them with enormous care, their creators covered them with clay: the act of composing and concealing mattered more than displaying the surface.
The material had travelled to the Gulf plain and remained immobilised beneath the soil. Burying so much valuable stone turned architecture into a reserve of memory and commitment, but we do not know what those who deposited it called themselves.
Hundreds of serpentine blocks were cut to comparable sizes and laid out to form large designs beneath Complex A. The investment included importing the rock, regularising each piece and mounting an image too extensive to be taken in from ground level.
The pavement was covered with clay shortly after being laid, so manufacture and concealment belonged to the same programme. Calling it a mask helps recognise a facial symmetry, although it may fix as a portrait what also admits geometric or cosmological readings.
Evidence and interpretation
Documented fact: excavations at La Venta uncovered massive offerings comprising pavements of rectangular greenstone blocks that had been deliberately buried. Interpretation and caution: calling them “masks” describes a visual resemblance; their supernatural identity, function and original audience remain debated. Additional documented evidence: excavations at La Venta recorded pavements of carefully arranged serpentine blocks buried as massive offerings. Further interpretation and caution: deliberate burial does not mean emergency concealment, and the supposed face does not by itself identify a specific supernatural being.

The deposit was also a vertical construction
The massive offerings at La Venta did not consist only of flat drawings of green stone. INAH describes large cavities, around fifteen by nineteen metres and up to seven metres deep, with tonnes of serpentine and clay and sand fill. Within those fills, additional votive sets could be placed; Offering 4 was associated with the fill of Massive Offering 3. The vertical dimension helps imagine the work of excavation, transport and closure. It also obliges us to distinguish the visible design of a pavement from the complete stratified deposit to which it belonged.
