No text transmitted. Raulin is probably not the same as Roelkin, see the critical comment to Roelkin, Et trop penser. Besides stylistic differences there is no common manuscript tradition.
According to Grove Music, Raulin is "known from the ascriptions of three songs in a Florentine manuscript (I-Fn Magl.XIX.176): a four-part setting of the monophonic song Je suis trop jeunette (ed. in MRM, ii, 1967) and the three-voice virelais Veu que tant (also in F-Pn fr.15123) and En elle croi." Grove gives other possible works written by him, which are included in IMSLP under the composer's name Roelkin.
