Trecena 19 runs from 1 Cuauhtli through 13 Mazatl, deer, its span carrying eagle, vulture, movement, flint, rain, flower, crocodile, wind, house, lizard and serpent before closing on the sign that opened Trecena 3 earlier in the count, now carrying the number thirteen, a third instance in the tonalpohualli's final stretch of a day sign returning at the higher number after having opened an earlier trecena at the first. As the second to last trecena in the twenty week sequence, this trecena's ambitious, bold reading under Xochiquetzal's patronage sits just before the count's final week, whose own augury of abundance and warning closes the full 260 day cycle, so the tonalpohualli's last three trecenas, sixteen through twenty setting aside the intervening Trecena 17 and 18, move through patience, penance, unsettled change and finally ambition before the count's last word on plenty shadowed by excess.
A reader working the tonalamatl in full sequence, as the tonalpouhque did when consulted for a comprehensive year reading rather than a single date, would have narrated this closing run of trecenas as building toward the count's final trecena rather than reading each in isolation. A client bringing a birth date from this closing run of trecenas to the tonalpouhque would have heard the reading placed explicitly against the count's approaching end, the diviner's craft treating position within the whole 260 day wheel as part of a date's meaning and not only the trecena and day sign taken alone.
