Gaston III of Foix-Béarn

Gaston Fébus [also spelt Phoebus] (30 April 1331 – 1391) was the eleventh count of Foix (as Gaston III) and viscount of Béarn (as Gaston X) from 1343 until his death.

Gaston was born either in Orthez or Foix, the eldest son of Gaston II/IX (1308–1343). As the lord's eldest son, he was given the name, Gaston. He later adopted Fébus as a nickname. In its classic spelling, Phoebus, it is one of the names of the sun-god, Apollo, and is apt because of Gaston Fébus's golden hair. His native language was Gascon (a dialect of Occitan), but he was also fluent in French. He wrote a treatise on hunting in French, and an Occitan song, Se Canta, has been ascribed to him. One contemporary records that he "very willingly spoke to me not in his native Gascon but in proper and elegant French".

Béarn had passed to the county of Foix in 1290. Fébus paid homage to the French king for his own county, but starting in 1347 he refused to give homage for Béarn, which he claimed as an independent fief, with its chief seat his stronghold at Pau, a site that had been fortified by the 11th century, which was later made the official capital of Béarn in 1464.

He was succeeded as count of Foix by Mathieu of Foix-Castelbon.

The House of Béarn-Foix was engaged in a long running feud with the House of Armagnac. In 1362, a battle was fought between the two noble houses at Launac. Fébus was victorious and succeeded in capturing his chief rivals, whom he ransomed for a vast fortune of at least 600,000 florins. This money was stored in the Moncade tower in Orthez, where Fébus also created a gallery of portraits and military trophies to commemorate the event.

In the 1380s, Jean Froissart visited the County of Foix and recorded the splendour of Fébus' court at Orthez. Fébus recorded the three "special delights" of his life as "arms, love and hunting"; he wrote an important treatise on the latter entitled Livre de chasse.
