The Fool is numbered 0, the number of unlimited potential, and does not actually have a specific place in the sequence of the Tarot cards. The Fool can come either at the beginning of the Major Arcana or at the end. The Major Arcana is often considered as the Fool’s journey through life and as such, he is ever present and therefore needs no number.
The Fool is shown at the beginning of his journey with unlimited potential. The sun rising up behind him represents the beginning of his journey. He is facing north-west, the direction of the unknown. He is looking upwards, toward the sky, or Spirit. He is about to step off a cliff into the material world but is he prepared? He has all the tools and resources he needs in the bag on his staff but he has not opened the bag yet. The white rose in his left hand represents purity and innocence. He has a guardian in the little white dog who will protect him throughout his journey but who will also push him to learn the lessons the Fool came here to learn. The mountains behind the Fool represent the realms of Spirit that he has just left and will spend his life trying to regain.
