The hand and heart referred to are the symbolic representations of the emotions of Ozymandias, the Egyptian king whose image was captured in the now-fallen sculpture. The traveller states that the sculptor read the emotions of the ancient king well and reflected them in the facial expression of the statue. Thus the "sneer of cold command" that the face of the statue depicts shows the "passions" that motivated the ruler's hands and heart. Just by looking at the facial expression, the traveller discerns that the king had a "hand that mocked them." In other words, he did not have kind and giving hands, or hands that protected his people. He reached his hands out in mockery, confirming to his subjects that they were worth little or nothing compared to his grandeur. Likewise, he had a "heart that fed." It was not a compassionate or loving heart, but one that preyed on his people, using them for his own gain and to satisfy his own desires. Interestingly, the parts of the statue that seem to be missing are the parts that contain the hands and the heart. The image is "trunkless." The head is visible, "half sunk," and the legs are still standing. But the traveller is able to extrapolate the missing pieces, the hand and the heart, from the expression the sculptor carved into the face.
