The Travels of Marco Polo

In 1017, an embassy was sent to the Court of China by Haji Sumutrabhūmi, “the king of the land of Sumutra” (Sumatra). The envoys had a letter in golden characters and tribute in the shape of pearls, ivory, Sanscrit, books folded between boards, and slaves; by an imperial edict they were permitted to see the emperor and to visit some of the imperial buildings.
