note: lauda incipit is ‘O amor contrafatto’ in pre-1450 sources like BML, Ashburnham 423, fol. 99r; lauda text entered in R2929, which was copied by 1448. The latter records two similar incipits, ‘O contrafatto amore/di carità ispogliato’ (no. 15), and ‘O amore contrafatto/ispogliato di virtute’ (no. 147), possibly the same lauda, though the latter is more commonly found in the Jacopone sources.
