a legendary creator pair, male (Cipactonal) and female (Oxomoco), at least as shown in the Codex Borbónicus, where the man sits with his knees up and the woman has her legs folded underneath her, and they are both somewhat toothless, indicative of their old age (as perhaps the first human couple).
See also the couple casting lots with maize kernels in the Florentine Codex, Book 4.
And see the mural remnant in Tlatelolco that seems to show this same couple.
ca tulteca catca in veuetque in oxomoco, in çipactonal, in tlaltetecuj, in xochicaoaca, in tlamatinj catca: in qujtztiaque, in qujximattiaque patli, in qujpeoaltitiaque ticiotl. = The old men Osomoco, Cipactonal, Tlaltetecui, Xochicaoaca, were Tolteca. They were the wise men who discovered, who knew of, medicine; who originated the medical art.
In late 1584, in the Tlaxcala area, a female healer, Magdalena Papalo, embodied the creator couple to help ease the delivery of a baby in childbirth.
