milli (Mdz36r)
This element of an agricultural field (milli) has been carved from the compound sign for the place name, Acamilixtlahuacan (see below). This milli is a horizontal, segmented rectangle, alternating in orange and purple. The segments have dots and backward C-shapes, which seem to suggest cultivation.
c. 1541, but by 1553 at the latest
