In Greek mythology, Pyrrhus is the grandson of what immortal nereid?
Achilles In Greek mythology, Achilles ( , ; ] ) was a Greek hero of the Trojan War and the central character and greatest warrior of Homer's "Iliad". His mother was the immortal nereid Thetis, and his father, the mortal Peleus, was the king of the Myrmidons.
Phineus (son of Belus) In Greek mythology, Phineus (Greek: Φινεύς , ] ) was a son of Belus by Anchinoe and thus brother to Aegyptus, Danaus and Cepheus. He had been engaged to Cepheus' daughter Andromeda before she wed Perseus, and Phineus plotted against him, leading Perseus to turn him and his co-conspirators into stone by showing them the head of Medusa. The affair appears to have formed part of Euripides' lost "Andromeda", but the sole extensive ancient treatment is found Ovid's "Metamorphoses".
