[Verginius Rufus]

The Wikipedia map shows a very large Lydia. Croesus, the last king of Lydia, supposedly ruled all the lands west of the Halys River (roughly the western half of Asia Minor), but Lydia proper was much smaller. Maps in J. B. Bury's old History of Greece show Phrygia up north, on the Asian side of the Hellespont, south of which is Mysia, then Lydia, then Caria in the SW corner of what is now Turkey. Lydia is shown as if not much more than 5,000 square miles. It included much of the valley of the Hermus River, also the Cayster River. The Meander River seems to be mainly in northern Caria, although part of it may have formed part of the boundary of Lydia.
