While the prisoner of Arcetri was thus eagerly fulfilling his great mission to his age, his friends were exerting themselves in vain to obtain at least an extension of his liberty. The Count de Noailles, French ambassador at Rome, had once attended Galileo’s lectures at Padua, and had become so enthusiastic an adherent, that he afterwards told Castelli that he must see Galileo once more before leaving Italy, even if he walked fifty miles on purpose.[492] He therefore united his efforts with Niccolini’s to obtain some amelioration for Galileo. But in vain. At an audience which Niccolini had on 8th December, 1634, Urban said indeed that he esteemed Galileo very highly, and was well disposed towards him; but all remained as before.[493] In the year 1634 the band of dauntless men, who again and again ventured to attempt to obtain Galileo’s liberty from the papal chair, was increased by the celebrated officer of state and man of learning, Fabri von Peiresc. Like Noailles, he had attended Galileo’s lectures at Padua,[494] had since been one of his most ardent admirers, and had long maintained friendly intercourse with Cardinal Francesco Barberini. Peiresc now interceded eagerly with this prelate for Galileo, and even ventured openly to say, in a long and pressing letter of 5th December, 1634, to Barberini:—[495] ... “Really such proceedings will be considered very harsh, and far more so by posterity than at present, when no one, as it appears, cares for anything but his own interests. Indeed, it will be a blot upon the brilliance and renown of the pontificate of Urban VIII., unless your Eminence resolves to devote your special attention to this affair....” On 2nd January, 1635, Barberini wrote a long letter in reply,[496] in which he was prolix enough on many subjects, but about Galileo he only made the dry remark, towards the end of the letter, that he would not fail to speak to his Holiness about it, but Peiresc must excuse him if, as a member of the Holy Office, he did not go into the subject more particularly. In spite of this, however, only four weeks later, Peiresc again urged Barberini, in a letter of 31st January,[497] to exert his powerful influence on behalf of Galileo. Peiresc justified his zeal by saying, “that it arose as much from regard for the honour and good name of the present pontificate, as from affection for the venerable and famous old man, Galileo; for it might well happen, by a continuance of the harsh proceedings against him, that some day posterity would compare them with the persecutions to which Socrates was subjected.”[498] Galileo, who had received copies of these letters, thanked Peiresc most warmly in a letter of 21st February, 1635, for his noble though fruitless efforts, and added the following remarkable words:—
