The name Thanatos is derived from the Greek word "thnetos", which means "mortal" or "subject to death". In some myths, Thanatos is said to have been created by the gods to bring death to mortals because they were becoming too powerful and immortal.
Thanatos was considered a powerful and feared god, but he was also seen as a necessary part of life. He was often invoked in prayers and rituals to ensure a peaceful and painless death.
