Read about the physical descriptions of each ghost of Christmas.
The ghost of Christmas Past is described as looking like a child but also like an old man. It has a delicate yet muscular figure, smooth skin, long white hair and a bright light coming from the top of its head. It wears a white tunic trimmed with flowers and a "lustrous," "glittering" belt that goes from bright to dark. It has a cap in one hand and a holly branch on another. Due to the fluctuating light, the ghost seems to have a shifting appearance, though it remains distinct at the same time.
The ghost of Christmas Present wears a loose green robe edged with white fur, a holly wreath with icicles and a rusted scabbard without a sword. Its hair is long, dark brown and curly, its eyes are "sparkly", and it is barefoot. Its face is described as "genial."
The ghost of Christmas Yet to Come is described as a "solemn" being that "seemed to scatter gloom and mystery." It wears a black garment that hides every feature of it except one hand. This garment makes the ghost hard to see when it is in a darkened place.
Read about how each of the ghosts acts in a given situation and certain surrounding facts about them. For example, the ghost of Christmas Present has more than 1,800 brothers and the ghost of Christmas Yet to Come never speaks and uses its hand to make gestures.
