Did you know?

In Greek mythology, Arachne was a weaver of such skill that she dared to challenge the goddess Athena at her craft. When she won their competition by weaving a tapestry disrespectful to the gods, the enraged Athena tore it to shreds, and in despair Arachne hanged herself. Out of pity, Athena loosened the rope, which became a cobweb, and changed Arachne into a spider. Today, the spiders, scorpions, mites, and ticks all belong to the class known as arachnids. Arachnophobia is the most common of the animal phobias; but many people suffer from similar phobias regarding snakes (ophidiophobia), dogs (cynophobia), and mice and rats (musophobia).
