According to his legendary
vida, he was the lover of Margarida or Seremonda (or Soremonda), wife of Raimon of Castell Rosselló. On discovering their affair, Raimon fed Cabestany's heart to Seremonda. When he told her what she had eaten, she threw herself from the window to her death. The vida precedes Cabestany's poem
Lo dous cossire in his
Chansonnier I. It is translated alongside the Old Occitan in Margarita Egan's 1984 edition
The vidas of the troubadours. Versions of this legend appear later in
Giovanni Boccaccio's
Decameron (1348–53),
Stendhal's On Love (1822), and in
Ezra Pound's Canto IV (1924–25). It also inspired the opera
Written on Skin (2012) by
George Benjamin and
Martin Crimp. Seremonda is thought to have been married two or three times, first to Raimon of
Castell Rosselló, to another husband in 1210, and then to Aymar de Mosset. De Mosset probably fought alongside Cabestany in the
Battle of Las Navas de Tolosa in 1212. Raimon himself lived peacefully in Castell Rosselló until at least 1218. Medievalist
John E. Matzke has identified at least fourteen different versions of the legend in several different literary traditions. Cabestany's
vida may not be the earliest version. With reference to regional historian Jules Canonge, Cabestany is presented as the archetypal troubador in
Ford Madox Ford's book
Provence. ==Known works==
