Malinalli, twisted grass, carries an augury built on the plant's own resilience: the grass is torn up and springs back, and the tonalamatl read the day in both movements at once, an augury of reversals, sickness and falls from favour, but also of the stubborn recovery of what was lost, a genuinely double reading rather than a simply unfavourable one softened only in passing. Sahagun's fourth book counts Malinalli among the ill omened signs overall, the difficulty of the fall weighing more heavily in the readers' summary judgment than the promise of recovery that followed it, a pattern the sources apply consistently: a sign's stated character in the Florentine Codex generally reflects which half of a double reading the compilers judged the stronger note, without erasing the gentler half entirely.
Malinalli's association with grass specifically, rather than a sturdier plant, marks it as a sign of resilience under genuine pressure rather than untested strength, since grass survives precisely because it bends and is torn rather than because it resists being torn in the first place, a distinction the readers' warning about falls from favour reflects directly. The sign opens Trecena 8, where Mayahuel's patronage of the maguey, another resilient plant surviving hard use, extends the same theme across the whole thirteen day week.
