Explanation:

It is noteworthy that the Maya, who had no metal instruments, made numerous articles from a thick and thick material, jade, especially a wide range of dress components, for example, belt plaques - or celts - ear spools, pendants, and furthermore covers. Celts were at times engraved with a stela-like portrayal of the lord.

The best-known case of a mask is presumably the demise cover of the Palenque lord Pakal, secured with sporadically molded jade plaques and having eyes produced using mother-of-pearl and obsidian; another passing veil, having a place with a Palenque ruler, comprises of malachite plaques. Thus, certain round and hollow vases from Tikal have an external layer of square jade circles. Many stone carvings had jade decorates.

wood carving remains today the primary sculptural art form of the sub saharan continent. african art history shows the earliest wooden sculptures from the 17th c are attributed to the kuba, central zaire but the earliest surviving sub-saharan sculpture is a zoomorphic head found in 1928 in central angola.
