GROTIUS, Hugo (1583-1645). Autograph letter signed ('H. Grotius') to Franciscus Sweertius [the Antwerp historian Pierre-François Sweerts], Paris, 3 September 1621, in Latin, expressing delight at praise of his work by Erycius Puteanus, though 'I do not so flatter myself as to qualify as worthy of such a eulogy something I wrote more as a consolation for my fate than as a proof of genius' [Non ita quidem mihi blandior ut quae in solatium magis casus quam in experimentum ingenii scripsi tanto elogio digner]; he promises to send Sweerts a copy of his 'Silva', though he has few left; the only news is that the king [Louis XIII] is striking at Montauban, though Grotius himself is among those who long for peace, one page, oblong 8vo (somewhat discoloured and worn); with a translation.
