The recueil in the Marienbibliothek at Halle/Saale containing the Tractatus logicalis published by Jacob van Breda at Deventer some time after IO April 1497 (see previous article), also contains another text by the same printer, a Tractatus de arte oratoria, published in 1506. The author of this little work is stated to be a certain Lucretius Bononiensis. The edition has never been described. Earlier editions of this text, including one of c. 1485 also printed by Jacob van Breda, make no mention of the author's name. It is possible that Luctetius Bononiensis is a pseudonym. In a work by Johannes Barclajus (1582-1621) there is a mention of a certain Lucretius, as pseudonym for a Dutch linguist. Perhaps the two Lucretiuses refer to one and the same person. The addition of'Bononiensis' would indicate that this Dutchman had studied at Bologna. Who was hiding behind this pseudonym is not determinable on the basis of the Tractatus de arte oratoria.
