A very well-known figure in Czech history, he served as Deputy Bishop of Prague during the reign of Vaclav IV. He was the first in the Catholic Church to become a martyr for sticking to the secrecy of his confession. Under Catholic Church rules, priests have a sacred duty of secrecy over the contents of the confession, and St. John was killed for refusing to reveal the contents of the queen's confession to the king. He was thrown into the river from the Charles Bridge. Legend has it that five stars appeared on his head when he was dying. From then on, the stars and the number five were regarded as symbols of Saint John. St. John is revered for his adherence to faith and moral principles, and is a saint against defamation and against the flood.

Poseidon (Greek: ∋οσειδῶν, English: Poseidon) is a Greek mythological sea god and one of the twelve Olympian gods. He was also the god in charge of horses. Legend has it that he gave humans the first horse, which was a golden chariot driven by a white horse. He was the brother of Zeus and Hades. Poseidon's image is usually described as a strong man wearing a sea god robe, holding a trident. He is in charge of the ocean, waves, marine life, and navigation, possessing strong power and the ability to control the ocean.
