1233–1242[1]) was a Provençal troubadour of the noble family of the Blacas, lords of Aulps, in the Empire.
[1][2] He was also distantly related to Charles I of Naples and Raymond Berengar IV of Provence.
A document of 1238 (two years after his father's death) mentions three sons of the elder Blacatz, two of which were named Blacacius.
[1] Eleven of his works survive, three sirventes, four cansos, and four coblas, including one single-stanza canso with a melody in F major, Ben volgra quem venques merces.
[1] This song was appended to a manuscript of the chansonnier du roi of Theobald I of Navarre in the early fourteenth-century.
