In all three of the following myths, from Ovid’s Metamorphoses, there is the concept of man’s pride and then his fall before God (in this case a god or several gods). He is then turned into a part of nature in punishment.
The first myth is Arachne and Minerva. Arachne is a woman who has been taught by the goddess Minerva to weave. She pridefully believes herself to be the best weaver. Minerva, her own pride hurt, challenges her to a weaving contest. Arachne wins. Enraged, the goddess changes Arachne into a spider (an arachnid), the most skilled weaver to this day.
Niobe is the second myth. Niobe is a haughty queen who has wealth, power, beauty and fourteen children. She discourages the people from worshiping the beautiful goddess Latona (also known as Leto), because she is jealous. The furious goddess retaliates by sending Phoebe and Phoebus (Apollo and Artemis) to kill the queen’s family. Finally, helpless and distraught, Niobe is turned into a weeping marble statue.
The last tale is Rustics turned to Frogs. The Rustics were the rude and unsophisticated people of the city. When the goddess Latona went to a pool to drink, they muddied the water in order to prevent her. Then, infuriated, she turns them into frogs. Since then, frogs have been muddying the pools and groaning about their misfortune.
