TOMMASO di PALMERSTOWN (Palmeranus or Palmerstonus, Th. de Hibernia or Hibernicus). - Theologian, erroneously believed to have been a Dominican or Franciscan, who obtained his bachelor's degree at the Sorbonne, of which he remained a member until 1330. He died before 1338, leaving his books and manuscripts to that university.
His works were widely circulated. *Religio mundia* (or *Tractatus de tribus punctis christianae religionis*, or *Expositio articulorum fidei christianae*), dated 1316, was published in Louvain in 1496; it is a kind of theological summa in three parts: articles of faith, precepts of the Decalogue, the seven capital vices, followed by an appendix on the power of the keys and censures. Posthumous is the *Manipulus florum*, a collection of sentences from 36 Greek and Latin Fathers on theological and philosophical problems, arranged alphabetically; many manuscripts, 13 editions, and numerous translations exist. Silvestro da Prierio reworked it under the title *Polyanthea novissima*, Vienna 1758; G. T. Ghilardi O. P. produced the latest edition (Mondovì 1858). Also posthumous is *Flores bibliorum*, on commonplaces from the Old and New Testaments, arranged alphabetically (Paris 1556, 1662; Lyon 1678-79). Manuscripts remain of: *De tribus sensibus Scripturae* and *De tribus hierarchiis tam angelicis quam ecclesiasticis*.
