in olden times, bread had various roles; that of survival, an indicator of financial strength, a commodity in a barter societal system.
‘Bread is often the focal point of complex religious ceremonies – we only have to cast our minds to the Christian Eucharist, in which sharing means belonging to a single ideal, ethical and moral way of life. In secular festivals the gift of food to guests celebrates the sense of the highest and most disinterested hospitality. A Sardinian proverb even states: those who have bread will not die of hunger. So let there be bread’.
