He did not consent to the building of a church on the land in question because it was adjacent to the church of Saint Tryphon in the Via della Scrofa.
Instead, the Pope simply entrusted the Church of Saint Tryphon to the Augustinians.
The small Church of Saint Tryphon had several relics.
Into it the tomb of Saint Monica, the mother of Augustine, was transferred in 1430 from the Augustinian church in Ostia, the town of her death.
The Church of Saint Tryphon was a titular church, i.e., symbolically assigned to a person appointed a bishop who had not been assigned a diocese to lead.
The privilege of being a titular church was passed on the Church of Sant'Agostino when that church was built.
The older Church of Saint Tryphon was kept as an annex to the Church of Sant’Agostino until finally demolished in 1736.
The Augustinians were not totally pleased with the decision of Pope Honorious that denied them the opportunity to build a church.
The Pope died, however, on 3rd April 1287. This was only eleven days after he had signed the document for the Augustinians.
