 The significance of the symbol has also been discussed by José Castillo Torre

After being introduced to the concept by Hunbatz Men, who discussed this concept in his 1986 book "Religión ciencia maya", Argüelles popularized Hunab Ku in his 1987 book "The Mayan Factor".However, instead of Martínez' symbol, what Argüelles asserted was the "Hunab Ku" symbol was originally a rectangular design used by the Aztecs for a ritual cloak, known as the Mantle of Lip Plugs (or, arguably, mantle of "spider water").The design survives today as a rug design being sold in central Mexico, but was associated with the Milky Way and the god Hunab Ku by Argüelles, who modified the symbol to look more like a circular motif evoking a yin and yang symbol as well as a spiral galaxy or the blood dropped by Hunab Ku on the bones that Quetzalcoatl took from Ah Puch to create humanity.
