However, the most reliably documented of these is the affirmation by German historian Dionysius Fabricius (1610) that Riga's name comes from its already established role in trade: "''Riga nomen sortita est suum ab aedificiis vel horreis quorum a litus Dunae magna fuit copia, quas livones sua lingua Rias vocare soliti.''"  (The name Riga is given to itself from the great quantity which were to be found along the banks of the Duna of buildings or granaries which the Livs in their own language are wont to call Rias.), the "j" in Latvian ''rīja'' (REE-eh) hardened to a "g" in German. English geographer Richard Hakluyt (1589) corroborates this account, calling Riga ''Rie'', as pronounced in Latvian.
