1. Control over the Sea: Poseidon has absolute dominion over the sea. He can summon violent storms, creating enormous waves and rough seas capable of capsizing ships and drowning sailors. His temper and emotional state are often reflected in the conditions of the ocean.
2. Earthquakes: Poseidon is known as "Earth-Shaker" because he can cause powerful earthquakes. These seismic events can bring about destruction, tsunamis, landslides, and damage to coastal communities and civilizations.
3. Sea Monsters and Creatures: Poseidon is associated with various sea creatures, including those considered monstrous, like the Kraken and Scylla. These mythical beings can be dangerous to humans, representing the untamed and unpredictable forces of the sea.
4. Drowning and Shipwrecks: Poseidon's authority over the sea means he can choose to drown sailors and cause shipwrecks. He may do so as punishment or if angered. Drowning poses significant danger to those traveling or living near water.
5. Underworld Connection: Poseidon is the brother of Hades, the god of the underworld. Some myths depict him as having a dark, underworld aspect, capable of unleashing demonic creatures from the depths of the sea.
6. Symbolic Significance: In literature and mythology, Poseidon often represents the uncharted and unpredictable aspects of human emotions, desires, and subconscious depths. His danger lies in the unpredictability of his nature and his power over primal forces.
7. Retribution: Poseidon's wrath is fierce, and he can be unforgiving toward those who incur his displeasure. Those who disobey him, disrespect him, or challenge his authority may face serious consequences.
8. Tides and Currents: Poseidon's control over the tides and currents can disrupt normal seafaring activities, making it difficult for sailors to navigate safely and potentially leading to accidents.
It's important to note that Poseidon is not inherently evil or malicious; he represents both positive and negative aspects of water's power and presence in the world. It is when his authority or natural order is challenged or disrespected that he can turn dangerous.
