Sologne (Secalaunia from Lat. secale, rye), a region of north-central France extending over portions of the départements of Loiret, Loir-et-Cher and Cher. Its area is about 5,000 square kilometres (1,900 sq mi), and its boundaries are on the north the river Loire, on the south the Cher and on the east the districts of Sancerre and Berry.
The Sologne is watered by the Cosson and the Beuvron, tributaries of the Loire, and the Sauldre, an affluent of the Cher, all three having a west-south-westerly direction. The pools and marshes which are characteristic of the region are due to the impermeability of its soil, which is a mixture of sand and clay.
The main towns of Sologne are:
In the middle of the 19th century Napoleon III led the way in the reclamation of swamps, the planting of pines and other trees and other improvements. Arable farming and stock-raising are fairly flourishing in the Sologne, but there is little manufacturing activity, the cloth manufacture of Romorantin being the chief industry. Game is abundant, and the region owes much of its revived prosperity to the creation of large sporting estates.
In the early 18th century, Jean-Philippe Rameau composed a famous harpsichord piece, Les Niais de Sologne, whose name translates as "the simpletons of Sologne". The form is a rondo with two episodes that are variations on the main section. Despite the title (which may allude to the meandering melody throughout), its use of ornamentation denotes a work of great subtlety and sophistication.
The book Le Grand Meaulnes by Alain-Fournier is set in the region of Sologne and mentions several places, such as Bourges and Vierzon. It is somewhere in this region where Meaulnes becomes lost and stumbles across the mysterious estate.
Also many stories and essays of Maurice Genevoix are set in Sologne.
