Final answer:
In Mayan art, 'lintels' are architectural blocks placed over doorways or between two vertical supports, often carved with significant inscriptions and imagery. The correct option is (C).
Step-by-step explanation:
In Mayan art, the term 'lintels' refers to blocks that go over a space created by two vertical supports, such as the area at the top of a doorway. These structural elements could be carved with inscriptions and reliefs that often depicted important events, rituals, or figures, including Mayan kings and their deeds.
Mayan art is known for its elaborate stone structures like pyramids and temples, which were often adorned with detailed carvings, including the famous stelae inscribed with the hieroglyphic script that provide an extensive historical record of their civilization. Carved from limestone, which is soft enough to be worked with tools but hardens over time, these works of art are integral to our understanding of Mayan culture.
