2007 Vatican 5 Euro Canticle of the Sun

For the 40th World Day of Peace, Vatican City issued this silver commemorative coin depicting Saint Francis of Assisi.

Benedict XVI wrote: "...humanity, if it truly desires peace, must be increasingly conscious of the links between natural ecology, or respect for nature, and human ecology. Experience shows that disregard for the environment always harms human coexistence, and vice versa. It becomes more and more evident that there is an inseparable link between peace with creation and peace among men. Both of these presuppose peace with God. The poem-prayer of Saint Francis, known as 'the Canticle of Brother Sun', is a wonderful and ever timely example of this multifaceted ecology of peace."
