From the Supplement to the Liturgy of the Hours for the Order of Preachers we read:
Blessed James was born at Mantua, Italy in the latter half of the thirteenth century. He entered the Order there and came to the notice of Nicholas Boccassini, Master of the Order, who made him his socius. Blessed James continued as his advisor when Nicholas was created cardinal in 1298 and when Nicholas became Pope as Benedict XI he was named bishop of Mantua in 1304. There he fought against the hatred and division which plagued the city. Because of his devotion to the poor during a time of pestilence and famine he was called "Father of the Poor." He died on November 19, 1332.
you established Blessed James as a model for your flock
and made him renowned for his zeal for peace
and for his mercy towards your people.
By his prayers and example
may we be united in the truth of your word
and ever ardent in your divine love.
We ask this through our Lord Jesus Christ, your Son,
who lives and reigns with you and the Holy Spirit,]
one God, for ever and ever.
