The recorded working language is medieval Latin, medieval Italian and Latin. The field of work recorded is hagiography, theology and Christianity. Works named in the authority record are Dies Irae, Vita beati patris nostri Francisci, Tractatus de miraculis, Memoriale in desiderio animae and Legenda sanctae Clarae virginis.

Thomas was born sometime between 1185 and 1190, into the noble family of the Conti dei Marsi at Celano in the Province of the Abruzzi. He received a sound liberal arts education, possibly at the Benedictine monastery of Saint John the Baptist near Celano. His familiarity with monastic tradition suggests that he may have studied at Monte Cassino, Rome or Bologna. He joined the Franciscan order probably in 1215. In 1221, he was present at the Pentecost Chapter at the Portiuncula, and then accompanied Caesar of Speyer on his mission to Germany. The following year he became custos of the convents at Mayence, Worms, Speyer, and Cologne, and soon after, Caesar of Speyer, on his return to Italy, made him his vicar in the government of the German province. Before September 1223, Thomas returned to Italy, and lived there in close contact with Francis.

Vita Prima: Soon after the canonization of Francis in 1228, Pope Gregory IX commissioned Thomas to write the Vita Beati Francisci ("The Life of Blessed Francis"; often called the "First Life"), a work on the saint's early life. Vita Secunda: A supplement, the Memoriale Desiderio Animae de Gestis et Verbis Sanctissimi Patris Nostri Francisci ("The Memorial of the Desire of a Soul Concerning the Deeds and Words of Our Most Holy Father Francis" often just called the "Second Life") was commissioned by Crescentius of Jessi, the Minister General of the Franciscan Order sometime between 1244 and 1247, and reflects changing official perspectives on Francis in the decades after his death. The third is a treatise on the saint's miracles, written sometime between around 1254 and 1257 at the bidding of Blessed John of Parma, who succeeded Crescentius as Minister General. Thomas's authorship of the three works on Francis of Assisi is well-established. Many researchers of the early history of the Franciscan order believe that Brother Leo, and Rufinus of Assisi, associates of Francis, were the source of the material for the Vita Secunda. Thomas also wrote Fregit victor virtualis and Sanctitatis nova signa in honor of Francis. Life of St. Clare of Assisi, on the early life of Saint Clare of Assisi, and the hymn "Dies Irae" are also traditionally attributed to him, but the authorship of both works is in fact uncertain.

In 1260 he settled down to his last post, as spiritual director to a convent of Clarisses in Tagliacozzo, where he died some time between 1260 and 1270. He was at first buried in the church of S. Giovanni Val dei Varri, attached to his monastery, but his body is now reburied in the church of S. Francesco at Tagliacozzo.
