atl (Mdz7v)
This element for water (atl) has been carved from the personal name Atonal. We have removed the four red circles relating to the part of the name that expressed tonalli (day, sun, or the solar animating force). This representation of water is a cross-section of a water channel, outlined in yellow, with curling ends, and filled with turquoise blue water.

Perhaps because this glyph had to be small, originally being attached to the head of the man whose name is Atonal, the water does not contain the wavy black lines that typically seem to show currents. We do see considerable interchangeability between atl and apantli (the latter being the canal or water channel), but the curling ends on right and left seem to be more common when the canal is a part of a date glyph.
