"Niebuhr observes that 'the words for a house, a field, a plough, ploughing, wine, oil, milk, sheep, apples, and others relating to agriculture and the gentler ways of life, agree in Latin and Greek, while the Latin words for all objects pertaining to war or the chase are utterly alien from the Greek.' Thus the apple-tree may be considered a symbol of peace no less than the olive." - 'Wild Apples', Henry David Thoreau.
"The vine is dried up, and the fig-tree languisheth; the pomegranate-tree, the palm tree also, and the apple-tree, even all the trees of the field, are withered: because joy is withered away from the sons of men." - 'The Bible', (multiple) authors unknown.
