The vast majority of figurines are simple in design, often nude or with a minimum of clothing, and made of local terracotta.
[3] It is thought, based on wooden busts recovered from the water-logged El Manati site, that figurines were also carved from wood, but, if so, none have survived.
More durable and better known by the general public are those figurines carved, usually with a degree of skill, from jade, serpentine, greenstone, basalt, and other minerals and stones.
[5] These ceramic figurines are easily recognized by the chubby body, the baby-like jowly face, downturned mouth, and the puffy slit-like eyes.
[11] Given the sheer numbers of baby-face figurines unearthed, they undoubtedly fulfilled some special role in the Olmec culture.
Michael Coe, says "One of the great enigmas in Olmec iconography is the nature and meaning of the large, hollow, whiteware babies".
It has been theorized that the elongated, flat-topped heads are reflective of the practice of artificial cranial deformation, as found in the Tlatilco burials of the same period or among the Maya of a later era.
It has been proposed that these figurines had multiple outfits for different ritual occasions – as Richard Diehl puts it, "a pre-Columbian version of Barbie's Ken".
[16] Offering 4 consists of sixteen male figurines positioned in a semicircle in front of six jade celts, perhaps representing stelae or basalt columns.
They had small holes for earrings, their legs were slightly bent, and they were undecorated – unusual if the figurines were gods or deities – but were instead covered with cinnabar.
Perhaps this particular formation represents a council of some sort—the fifteen other figurines seem to be listening to the red granite one, with the celts forming a backdrop.
[24] Despite the many stylised figurines, Olmec-period artisans and artist also portrayed humans naturalistically with "a most extraordinary realistic technique".
[28] In a 1999 article, Carolyn Tate and Gordon Bendersky analysed head-to-body ratios and concluded that these figurines are naturalistic sculptures of fetuses, and discuss the possibility of infanticide and infant sacrifice.
