The irony of discoveries
Scientific innovations and discoveries are made by experts who have done extensive research studies and experiments based on their specific fields. The paradox in the entire exploration is that Columbus makes scientific discoveries and recordings despite being not a scientist. For instance, Columbus is the first person to make recordings about magnetic inclination. Additionally, Columbus is the first individual to estimate the traveling distance in the sea. Consequently, the reader finds it paradoxical that a man who never attended a science class can make very powerful and historical scientific discoveries that transform how the world operates.
The crew
Sailing is one of the professions that require courage and confidence. Since the crew spends most of its time in the deep seas, the sailors must always be positive and vigilant. Satirically, the ship's crew in this context depicts a worrying attitude and character. For instance, the nervousness and fear among the crew sound sardonic. Instead of encouraging the captain to continue moving towards the destination, the crew is worried. The crew's fear demoralizes the captain, who is supposed to remain alert and strong despite the turbulence and threatening waves.
The irony of Columbus
When readers are introduced to Columbus, they see him as an explorer who traveled the world and documented the major events and happenings that can inspire current and future generations. According to the author, Columbus wants to explore and share his experiences with the world. Paradoxically, Columbus had a hidden agenda in his mission because he wanted to raise funds from well-wishers and institutions to promote his businesses and increase his wealth. These revelations towards the end of the journal contradict the picture painted earlier that Columbus' mission was to enlighten the world.
