 Reginald is also considered by some as the compiler of the Supplement to the "Summa Theologiae".This supplement was meant to afford completion to the unfinished "Summa Theologiae", and it was composed out of book IV of Aquinas's "Commentary to the Sentences".The funeral discourse published at Bologna in 1529 under the name of Reginald is the work of the Italian humanist Joannes Antonius Flaminius.
