matl (T1871:1)
This element of the land measure unit (matl or cematl) looks like a hand. It is a part of a measurement of a parcel on a land document. The sign is so small (magnified here) the coloring is difficult to determine. The hand is upright. The thumb is on the viewer's left (so likely a left hand). Only the thumb and three fingers are visible.

Matl is often associated more with measurements of an arm's length or even two arms outstretched, from hand to hand, than the literal dimension of the length of a hand. Similarly, the term maitl could mean hand or arm. In the context of the manuscript here, this hand is paired with a red banner, which would refer to 20 matl or cempohualmatl, and there are another 10 ones nearby, for a total measurement of 30 matl.
