Meridiano di Francia, dal trattato "De la grandeur et de la Figure de<br />
la Terre", pubblicato nel 1723 da Jacques Cassini<br />
Cassini merdian as published in 1723 "Traité de la grandeur et de la<br />
Figure de la Terre"<br />
senza successo, deve però attendere ancora altri quattro<br />
anni, dopo la pubblicazione della sua seconda versione,<br />
dal titolo Epistolarum mathematicarum fasciculus (1729),<br />
perché da esso Pierre-Luois Moreau de Maupertuis (1698<br />
- 1759) prenda spunto per la pubblicazione del suo<br />
saggio Sur la figure del la terre (1733), col quale incita gli<br />
scienziati dell’epoca a compiere tutti gli sforzi operativi<br />
possibili per giungere a dirimere la “questione geodetica”,<br />
abbandonando le mere speculazioni filosofiche, che non<br />
avrebbero approdato a nulla di nuovo.<br />
itself to be far more difficult to ascertain than latitude, the<br />
measurement of the arc of a meridian at different latitudes<br />
appeared to be the best choice. By initiative of the Académie<br />
Royale des Sciences de Paris, two famous expeditions to<br />
Lapland and Peru were financed. The first one to leave was<br />
the one directed to Peru (1735), with Louis Godin (1704-<br />
1760), Charles-Marie de La Condamine (1701-1774), and<br />
Pierre Bouguer (1698-1758), and the second one, followed<br />
in 1736, to Lapland, leaded by Pierre-Louis Moreau de<br />
Maupertuis (1698-1759). Thanks to them, the Newton’s<br />
theory was confirmed once and for all by the empirical data<br />
and it was recognised as the truth: the Geodetic Revolution<br />
is started and new, unexpected perspectives are opened for<br />
the cartographical science.<br />
Another step towards a geometrical cartography on a<br />
topographical scale for wider territories is taken thanks to the<br />
