Key Discussion Points and Insights

1. Discovery of the Aztec Death Whistle

• In the late 1990s, archaeologists excavated an Aztec temple dedicated to the wind god Ehecatl in Mexico City and found the remains of a 20-year-old male who had been beheaded, squatting at the base of the stairway, holding two musical instruments—later identified as death whistles.
  • Josh: "If you go to Mexico City, you should know that you are a lot of times standing on the ruins of ancient burial temples… In the late 90s they excavated a temple dedicated to the Aztec wind god… and uncovered the remains of a 20-year-old male… holding a couple of musical instruments." (01:17)

2. Significance of the Find

• The National Museum of Anthropology in Mexico City is recommended for its display and preservation of such discoveries.
• Everyday life sits atop centuries of history; people had unknowingly been walking over these remains for years.

3. Symbolism and Deities

• The whistles were engraved with skulls and believed to represent a union between two Aztec gods:
  • Mictlantecuhtli: god of death and the underworld.
  • Ehecatl: god of wind.
• Represented a blend of life and death forces.
  • Chuck: "What they think this whole thing represents is the combination between Ehecatl and Mictlantecuhtli… two very powerful gods…” (02:35)

4. Mispronunciation and Cultural Sensitivity

• The hosts discuss common mispronunciations and the importance of responsible sharing of cultural knowledge.
  • Chuck: "If you're not sure how to pronounce something, don't make a video telling other people how to pronounce something." (03:41)
  • Josh: "We mispronounce stuff on this show… but we don't tell people we're pronouncing it right." (03:48)

5. Myth vs. Research: Whistle’s Use in Battle

• Myth: The whistles were used en masse by Aztec warriors to terrify enemies.
• Research: Music archaeologist Arnd Adje Both analyzed the instruments and found ceremonial, spiritual uses more probable.
  • The original whistles were tiny and unremarkable in sound; Both created larger replicas (using CT scans) to study their acoustic properties as "air spring whistles"—unique to pre-Columbian America.
  • Josh: "He was the first person to actually play them… and he apparently… was like, these suck. These are terrible death whistles." (05:02)

6. Technical Aspects of the Whistle

• Made with an internal air-spring design for a distinctive, distorted, breathy noise.
• Players can cup their hand over the end to modulate the sound, but the instrument is completely unlike any Western wind instrument.

7. Ritual Purpose and Spiritual Journey

• In Aztec cosmology, the journey to the underworld took nine years and required the deceased to cross a wind-whipped field, symbolized by obsidian blades.
• The death whistles, found alongside obsidian blades and a ritual bowl, likely played a role in guiding souls through this perilous spirit journey.
  • Chuck: “In that Aztec tradition, when someone dies, it’s a pretty perilous route… A large field being whipped by a wind… in the Codex Borgia, those winds are represented by obsidian blades.” (10:06)

8. Primary Source: Codex Borgia

• The connection between the wind and death gods is depicted in the illustrated Codex Borgia, an ancient manuscript describing Aztec deities and rituals, affirming their roles as guardians of the underworld.
• The depiction supports the combined symbolism found in the whistles.

9. Death Festival and Evidence of Use

• The festival of Toxcatl (Tochcottl), as described by folklorist Lewis Spence in 1913, featured the beheading of a youth carrying the death whistle, which was sounded like “the weird wind of night.”
  • Josh, quoting Spence: "He carried also the whistle, symbolical of the deity lord of the night wind, and made with it a noise such as the weird wind of night makes when it hurries through the streets." (11:49)

10. Debate About Battlefield Usage

• The hosts dismiss the popular notion that these small whistles were terrifying weapons of war.
  • Chuck: "This is the size of my pinky... even 300 of these isn't gonna scare anybody." (13:32)
  • Large drums and conch shells—yes; tiny death whistles—no.
