Itzcuauh (MH499v)
This black-line drawing of the compound glyph for the personal name Itzcuauh (perhaps meaning "Golden Eagle" is attested here as a man’s name) shows an upright obsidian blade (itztli) curving toward the right and, above that, an eagle's head in profile, looking toward the viewer's left. The eagle (cuauhtli) has tufts of feathers sticking up all around its head. Its beak may be open. If Itzcuauh is not short for itzcuauhtli, golden eagle, then another possibility could be a partially phonetic rendering of itzcuahuitl, the obsidian-bladed club, and in that case the eagle's head could be a phonetic indicator for wood (cuahuitl).

The man's name, Itzcuauh, was also held by one of Moctezuma's lords who played a vocal role during the Spanish invasion of the capital, and it was the name of an actual bird that, according to Clavijero (1844), not only hunted other "large birds and hares, but it also attacks wild beasts and men." The context image for this glyph shows that Martín Itzcuauh worked in textiles, for there is a spindle above his name.
