Celio Calcagnini

[1] He had a wide experience: as soldier, academic, diplomat and in the chancery of Ippolito d'Este.

He was consulted by Richard Croke on behalf of Henry VIII of England in the question of the latter's divorce.

[2] He was a major influence on Rabelais's literary and linguistic ideas and is presumed to have met him in Italy, as well as being a teacher of Clément Marot[3] and was praised by Erasmus.

[5] His Quod Caelum Stet, Terra Moveatur is a precursor of the De Revolutionibus of Copernicus, though A. C. Crombie qualifies his rotational theory as "vague",[6] and is often dated to about 1525.
