Lost King Of The Maya

K'inich Yax K'uk' Mo' (lit. "Great-Sun First/Green Quetzal Macaw", ruled 426 – ca. 437) is named in Maya inscriptions as the founder and first ruler of the pre-Columbian Maya civilization polity centered at Copán, a major Maya site located in the southeastern Maya lowlands region in present-day Honduras. The motifs associated with his depiction on Copan monuments have a distinct resemblance to imagery associated with the height of the Classic-era center of Teotihuacan in the distant northern central Mexican region, and have been interpreted as intending to suggest his origins and association with that prestigious civilization. One of the most commonly cited motifs for this interpretation is Yax K'uk' Mo's 'goggle-eyed' headdress he is commonly depicted with, seemingly an invocation of the northern central Mexican rain deity known as Tlaloc to later peoples such as the Aztecs. However, modern strontium isotope analysis of the human remains recovered from the tomb attributed to him indicate that K'inich Yax K'uk' Mo' spent his formative years much closer to Copan, at Tikal, and had not himself lived at Teotihuacan.
