It has been suggested that En Gui (v. 49) is to be identified with Count Gui V of Forez who took part in the 1248 crusade of Louis IX (Cura Curà, p. 10, referring to Oscar Schultz-Gora, «Die Lebensverhältnisse der italienischen Trobadors», Zeitschrift für romanische Philologie, 7, 1883, pp. 177-235 on pp. 178-179; Kurt Lewent, «Das altprovenzalische Kreuzlied», Romanische Forschungen, 21, 1905, pp. 321-448, on p. 419; Kolsen, Trobadorgedichte, p. 71 and Alfred Jeanroy, La Poésie lyrique des troubadours, 2 voll., Toulouse and Paris 1934, vol. I, p. 434). The troubadour sends another song, Si anc me fes Amors que·m desplagues (BdT 456.2), which echoes the first line of the present piece, to a lord Isnart (v. 51; Cura Curà, p. 28), who has been identified with the nobleman and troubadour Isnart Entrevenas, eldest son of Raimon II d’Agoult and Isoarda de Dia. Isnart’s dates are given as 1191 – c. 1239/40 by Florian Mazel (La Noblesse et l’Eglise en Provence, fin Xe-début XIVe siècle. L’exemple des familles d’Agoult-Simiane, de Baux et de Marseille, Paris 2002, p. 619) and by Martin Aurell as 1197-1244 (La Vielle et l’épée. Troubadours et politique en Provence au XIIIe siècle, Paris 1989, p. 85). If it is assumed that Uc’s two songs date from approximately the same period, it seems more likely, as Saverio Guida and Gerardo Larghi suggest (Dizionario Biografico dei Trovatori, Modena 2013, pp. 516-517 and pp. 303-304), that seign’en Gui is to be identified as Gui IV of Forez, who took part alongside Frederick II Hohenstaufen in the crusade of 1228. In this case the tornada would date from after Frederick sailed from Brindisi to Cyprus on 28 June 1228 and before he arrived back in Brindisi on 10 June 1229 (Steven Runciman, A History of the Crusades, 3 voll., Harmondsworth 1971, first published Cambridge 1951-1954, vol. III, pp. 179-192), and the rest of the song from the same time or earlier.
