  • Boscovich also wrote to J. N. Delisle about the excitement and gullibility of the Roman populace at the time of the solar eclipse in July, 1748, especially if rumours about the celestial display could be attributed to the scientific clerics: ‘. .. et encore dans les conversations de la Noblesse on prenoit plaisir de mettre dans ma bouche et dans cette des pères Minimes des extravagances pour se divertir des simples. Il est bien vray qu'un grand nombre de Gens instruits sçavoient à quoy s'en tenir, et que par curiosité astronomique ils se mirent à observer. A peine y‐a‐t‐il eu une Maison dans laquelle ou avec des Verres colorez ou avec des Lunettes ou avec de l'eau ou d'une autre manière on ne l'aye regardé. Plusieurs ont terminé leurs observations par de bons diners et des conversations joyeuses . ..’ Observatoire de Paris: Mss. B.1.4.

  • It is worth speculating more seriously on the role of amateurs in the state of science in eighteenth century Italy and how their contribution encouraged or hindered progress and to what extent the gentleman‐dilettante was concerned with ideological questions underlying scientific endeavour.

  • Boscovich was little interested in the map itself, according to Maire: ‘je rendray conte de cet ouvrage [the map] et de celui de la méridienne dans un même ouvrage. Il sera facile au P.

  • 1, No. 183: 75, quoting the French astronomer Jérome de Lalande), is shown by the anecdote recounted by Maire's friend in Rome, Father John Thorpe:
  • ‘When Fr. Maire was engraving his map of the States of Urbino for Cardinal Legate Stoppani, his Eminence desired him to join Fr. Boscovich's name, to give it credit. The true author, Fr. Maire, answered that, as he himself would think it an affront to be called a joint author if he had no hand in it, so he thought Boscovich might take it amiss to have his name so placed; but if the Cardinal desired it, he would mention that the map had been drawn from observations in which Boscovich was concerned, to which wonderful humility of Maire's the Cardinal acquiesced . ..’
  • Thorpe further notes that the only recompense Maire received for this map was a present of twelve copies, and remarks, ‘This is Roman generosity, but the Cardinal adds that if he can do Fr. Maire any Service, he may signify it to his Eminence. This is enough to give anyone the Spleen...” Stonyhurst College: Ms. E.II.51, Thorpe‐Jenison Correspondence. Thorpe to Jenison, 12 February 1757.
