"If our diagnosis is correct, this implies that Down’s syndrome is not a modern disease," say [Levitas and Reid] (American Journal of Medical Genetics 2003;116:399-405).
The diagnosis of Down’s syndrome in the angel was based on a number of features: a flattened mid-face, epicanthal folds, upslanted palpebral fissures, a small and upturned tip of the nose, and downward curving of the corners of the mouth. The hands, crossed over the breast, have short fingers, especially on the left.
