The Pleiades (Tianquiztli) are portrayed in the upper left
of the document. The other symbols represent other constellations, a meteor or shooting star, the sun, the moon, the eclipses. The image is from the Primeros
Memoriales, a sixteenth-century colonial manuscript compiled by Fray Bernardino de Sahagun.
