Saint Francis of Assisi (Giovanni Francesco di Bernardone; 1181/1182 – October 3, 1226) was a Catholic deacon and preacher. He also was the founder of the Order of Friars Minor, more commonly known as the Franciscans. He is known as the patron saint of animals, the environment and one of the two patrons of Italy (with Catherine of Siena), and it is customary for Catholic churches to hold ceremonies blessing animals on his feast day of 4 October. The term Franciscan is most commonly used to refer to members of Catholic religious orders, founded by Saint Francis of Assisi. As well as Roman Catholic there are also small Old Catholic and Anglican Franciscan communities. It can also be applied to ideals he inspired in many movements in the modern age.
Thomas of Celano (Italian: Tommaso da Celano; c. 1200 – c. 1260-1270) was an Italian friar of the Franciscans (Order of Friars Minor), a poet, and the author of three hagiographies about Saint Francis of Assisi.
