The book opens with a preface describing his father and uncle traveling to Bolghar where Prince Berke Khan lived. A year later, they went to Ukek[56] and continued to Bukhara. There, an envoy from the Levant invited them to meet Kublai Khan, who had never met Europeans.[57] In 1266, they reached the seat of Kublai Khan at Dadu, present day Beijing, China. Kublai received the brothers with hospitality and asked them many questions regarding the European legal and political system.[58] He also inquired about the Pope and Church in Rome.[59] After the brothers answered the questions he tasked them with delivering a letter to the Pope, requesting 100 Christians acquainted with the Seven Arts (grammar, rhetoric, logic, geometry, arithmetic, music and astronomy). Kublai Khan requested that an envoy bring him back oil of the lamp in Jerusalem.[60] The long sede vacante between the death of Pope Clement IV in 1268 and the election of his successor delayed the Polos in fulfilling Kublai's request. They followed the suggestion of Theobald Visconti, then papal legate for the realm of Egypt, and returned to Venice in 1269 or 1270 to await the nomination of the new Pope, which allowed Marco to see his father for the first time, at the age of fifteen or sixteen.[61]
