Why did Egyptian Paintings only show right hands?

Egyptian paintings typically depicted figures with their right hands forward to symbolize power and authority, as the right side was considered more auspicious and associated with positive qualities. This artistic convention also adhered to the cultural norms of showing a person's most recognizable features while maintaining a consistent style across representations. By emphasizing the right hand, artists ensured that the figures conveyed their significance and roles clearly within the context of the artwork.
