The discussion centers around the existence of flying snakes mentioned by Herodotus, with participants debating their credibility and the reasons for their extinction. One viewpoint suggests that these snakes were beneficial to spice collectors as they deterred thieves, while another argues they were ultimately killed off by Egyptians and ibises. There is speculation about how spice collectors might have used smoke from frankincense to drive the snakes away. The conversation also touches on the broader implications of Herodotus' reliability as a source, with some participants expressing skepticism about the acceptance of his accounts compared to modern scientific theories. The lack of Egyptian carvings depicting flying snakes is highlighted as a significant point against their existence, raising questions about what evidence would be necessary to validate such claims. Overall, the dialogue reflects a mix of historical analysis, speculation, and the challenge of reconciling ancient reports with contemporary understanding.
