Andrea Argoli

Andrea Argoli[1] (1570–1657), born in Tagliacozzo, was a versatile Italian scholar. He was a jurist, mathematician, astronomer and astrologer, and medical writer.[2] His father was Ottavio and his son, Giovanni.[3]

He was professor of mathematics at the University of Rome La Sapienza, from 1622 to 1627, and then the University of Padua 1632 to 1657. His astrology pupils may have included Placido Titi,[4] and Giovanni Battista Seni, astrologer to Wallenstein.


Andrea Argoli was born at Tagliacozzo in the Kingdom of Naples about 1568. He studied medicine and astronomy; and all that is known of him is, that he was obliged to leave his country by the efforts of those who were hostile to him, some say for his talents, others for his astrology; that retired to Venice, the Senate of which made him professor of mathematics at Padua; and that he died at Padua later than 1650. The astronomical ephemerides which he published, extending as far as the year 1700, gave an extent and permanence to his reputation which his other writings would not have obtained alone. Delambre (Astr. Mod. vol. ii. p. 514) has bestowed three pages upon Argoli, who, it appears, was not well informed on what had been done in his own time, and is aptly described as “one of those laborious men who wrote long works for the use of astronomers, and particularly of those who were also astrologers.” His opinion that logarithms only facilitated easy operations, but made complicated ones more difficult, is better worth preserving for its singularity than any one of his writings for its utility.
