Inerrantium stellarum significationes
An astrometeorological parapegma arranged according to the twelve months from January to December. The text was translated from the Greek by Niccolò Leonico Tomeo (1456-1531) and first published in Venice in 1516. Whereas it shares the subject matter with the parapegma contained in Book II of the Phaseis (A.4), this text has nothing to do with Ptolemy, as Denis Petau had already recognised in his notes to his translation of the Phaseis (A.4.2, see ed. Paris 1630, sig. 415-416). This parapegma is in fact a translation of the so-called ‘Clodius Tuscus parapegma’ sometimes attributed to Ptolemy. All editions and manuscripts listed below end incomplete on 23 December, except ed. Schwäbisch Hall 1539, where the entries for 24-31 December do correspond to the Greek text. This Schwäbisch Hall edition also gives an altered name for the translator: ‘Leonicenum’ instead of ‘Leonicum’.
The extraordinary editorial success of this text is due to the fact that it was published together with Ovid’s works. The exceptions are Basel 1533 (astrological compendium), Wittenberg 1534 (stand-alone), Basel 1541 (Ptolemy’s works), Basel 1542 (with Ambrogio Calepino’s Latin dictionary), Basel 15512 (Ptolemy’s works), Basel 15513 (astrological compendium) and Paris 1630 (Denis Petau’s Uranologion). The list of early printed editions below includes only those which I have been able to see. It is incomplete for the sixteenth century and no attempt has been made to locate post-1600 copies.
