Which artistic discipline did Michelangelo primarily focus on?

Michelangelo is renowned for his extraordinary contributions across multiple artistic disciplines, including painting, sculpture, and architecture, which is why the answer is inclusive of all these areas. Originally trained as a sculptor, he created some of the most famous sculptures in Western art, such as "David" and the "Pietà," showcasing his mastery of form, anatomy, and the human experience.

In addition to his sculptural work, Michelangelo is highly celebrated for his painting, most notably the frescoes on the ceiling of the Sistine Chapel, where he demonstrated his profound ability to convey narrative and emotion through color and composition. His work on the Last Judgment altar, also in the Sistine Chapel, further exemplifies his skill as a painter.

Furthermore, as an architect, Michelangelo played a crucial role in the design of St. Peter's Basilica in Rome, influencing Renaissance architecture with his innovative approaches. His holistic engagement in these three artistic disciplines underscores his versatile genius, making it accurate to state that he focused on all of the above.
