The huehuetlahtolli, “the old words,” are Nahua exhortations in which parents and elders counsel the young. A study published by the Institute of Historical Research of UNAM credits the work of collecting them to the Franciscan friar Andrés de Olmos: “la labor de indagar sobre ellas y hacerlas copiar fue, sin duda, de fray Andrés de Olmos” (the work of seeking them out and having them copied was, without doubt, that of Friar Andrés de Olmos).
In an old Spanish rendering, one father’s exhortation begins: “Hijo mio… has salido á luz del vientre de tu madre como el pollo del huevo” (My son, you have come into the light from your mother’s womb like the chick from the egg).
