Egyptian decorative art
(1895)
“ The vulture alone as the emblem of protection is frequently figured with outstretched wings across the ceilings of the passages, particularly those of the royal tombs of the XIXth dynasty. There is perhaps no sight in the animal world more imposing than one of these birds, stretched out with a span of some nine or ten feet, hanging in the air close overhead; it is natural that it should have excited the admiration of man, and not being hurtful it readily came to be honoured as a type of maternal care. ”
