Describe the Spirit of Christmas Past.

From the text:

. . .figure--like a child; yet not so like a child as like an old man . . . Its hair, which hung about its neck and down was white as if with age; and yet the face had not a wrinkle in it, and the tenderest bloom was on the skin. The arms were very long and muscular; the hands the same, as if its hold were of uncommon strength. Its legs and feet, most delicately formed, were, like those upper members, bare.
