Query: Who invited Dominic to stay in the Roman Basilica of Santa Sabina?
Context: In 1219 Pope Honorius III invited Saint Dominic and his companions to take up residence at the ancient Roman basilica of Santa Sabina, which they did by early 1220. Before that time the friars had only a temporary residence in Rome at the convent of San Sisto Vecchio which Honorius III had given to Dominic circa 1218 intending it to become a convent for a reformation of nuns at Rome under Dominic's guidance.
