Frances Karttunen: 

MAN(I) irregular verb; prêt: MANCA for something flat to cover a surface, as water in a shallow pan, etc. / estar cosas llanas (C) M has the phrase nican mani with the gloss ‘here is the book, plate, or pan of water.’ There is a locative suffix –MĀN which, though close in sense, has a long vowel in its attestations in C. Z consistently has the corresponding vowel in MAN(I) long, but there is agreement across the other sources that the verb has a short vowel. See MAN(A). MANCA See MAN(I).

With lands, mani comes down to "to be." It used to have the meaning of being spread out. But in testaments, mani is more often associated with tlalli than ca or onoc or anything similar. Personal communication from James Lockhart

mantica = at (located at)

Mani can also have a temporal location meaning, as with dates, i.e. in or on such and such a day. But we don't translate it when it means day -- just say the 13th, or whatever number. For example, we see "ic 22 ilhuitl mani de Junios 1586 años" (the 22nd of June, 1586) in the Nahuatl baptismal records from Tlatelolco.
