ACHILLINI, Claudius, grandson of the former, read lectures at Bologna, Ferrara, and Parma; where he was reputed a great philosopher, a learned divine, an excellent lawyer, an eloquent orator, a good mathematician, and an elegant poet. He accompanied Cardinal Ludovino, who went as legate into Piedmont; but being afterward neglected by this cardinal, when he became pope under the name of Gregory XV. he left Rome in disgust, and retired to Parma; where the duke appointed him professor of law, with a good salary. A canzone which he addressed to Louis XIII. on the birth of the dauphin, is said to have been rewarded by Cardinal Richlieu, with a gold chain of the value of 1000 crowns. He published a volume of Latin letters, and another of Italian poems, which gained him great reputation. He died in 1640, aged 66.
