Final answer:
According to Bernard Evslin's book, Greek myths, particularly the Gigantomachy, serve as explanations for natural phenomena like volcanic eruptions and earthquakes, reflecting the actions and conflicts of deities like Zeus.
Step-by-step explanation:
In Heroes, Gods and Monsters of the Greek Myths by Bernard Evslin, we are meant to infer that mountains still explode in fire and the earth still quakes because these are manifestations of the mythical battles and the turbulent dynamics among ancient Greek deities. The Greeks explained natural phenomena through the actions and the conflicts of the gods. For instance, volcanic eruptions and earthquakes could be seen as the ongoing effects of the Gigantomachy, the battle between the Olympian gods and the Giants, or due to the wrath and might of gods like Zeus, who wielded the thunderbolt and was capable of shaking the earth.
The myths served not only as entertainment but also as a framework for understanding the natural world, attributing divine causes to natural events. This helped to explain the seemingly random and chaotic aspects of nature by framing them within the context of a cosmic narrative shaped by powerful deities with very human-like attributes and emotions.
