a mountain (volcano) near Tlaxcala, named for the goddess of ground waters (rivers and lakes) or feminine waters (as opposed to celestial waters, governed by Tlaloc); as such, she is related to Chalchiuhtlicue (Jade Skirt) the goddess of this type that is represented in the Codex Borgia; the mountain is also known as Malintzin and Malinche today (see attestations)
The Tepexic Annals pair this volcano/goddess, Matlalcueye, with the hoary old man volcano, Poyauhtecatl (the Orizaba volcano), much as Iztaccihuatl (female) is paired with Popocatepetl (male).
Matlalcueye = "woman who had blue skirts" (García Garagarza translation, 2023)
Matlalquaie [Matlalcueye]: "tlaxcallan in ca, tachcauh, vei, veipol, veitepul, tepeuhtica, toiauhtica, veca tlacçatica, xixipuchtic, xixiqujpiltic, vacaltic, vacaliuhquj." [Tlaxcallan in ca, tachcauh, huei, hueipol, tepeuhtica, toyauhtica, hueca tlaczatica, xixipochtic, xixiquipiltic, huacaltic, huacaliuhqui. (Orthographic update by SW)] = "It is by Tlaxcalla. It is a principal one, large, big, huge. It is radiating, outspread, going far out, rough, uneven, with ravines, with gorges." (Anderson & Dibble translation)
