Born at Hamburg in 1596, he studied at the gymnasium of Hamburg, and later at Leyden University, where he was closely acquainted with some of the most famous scholars of the age, including Johannes Meursius, Daniel Heinsius and Philip Cluverius, whom in 1618 he accompanied on his travels in Italy and Sicily, thus giving him a taste for the study of geography. Disappointed at his failure on his return to obtain a post in the gymnasium of his native Hamburg, he left Germany for good. Having spent two years from 1622 in England, at Oxford and London, gathering materials for his Geographi Minores, he then proceeded to Paris.
At Paris in 1624, he became librarian to the President de Mesmes, the friend of the scholarly brothers Dupuy, and the correspondent of N. Peiresc. At this time he was converted to Catholicism. It seems that it was the liking he had always displayed for Platonic philosophy impelled him to read eagerly the Greek and Latin Fathers, especially those who treated of contemplative and mystical theology that led him to this step.
In 1627 he went to Rome, and through the influence of Peiresc was admitted to the household of Cardinal Francesco Barberini, former papal nuncio and the possessor of the most important private library in Rome. In 1636 he became the cardinal's librarian.
Finally, under Innocent X, he was placed over the Vatican Library. The popes sent him on various honorable missions, such as bearing the cardinal's hat to the nuncio at Warsaw in 1629, and Alexander VII sent him to Innsbruck to receive abjuration of Protestantism by the mercurial and tiresome Christina, former Queen of Sweden. He also acted as intermediary in the conversion of the Danish nobleman, the Landgrave of Darmstadt and of Ranzau.
Mostly, however, he was occupied with his studies. Holstenius formed great projects. He was a man of unwearied industry and immense learning, but he lacked the persistency to carry out the vast literary schemes he had planned. Among them, he desired to correct Cluver's errors and complete his work; to edit, translate and comment the works of the Neoplatonists; to form a collection of the unedited homilies of the Greek Fathers; to collect inscriptions; to write a critical commentary on the Greek text of the Bible; to form a collection of all the monuments and acts of the history of the popes. These diverse undertakings consumed his energies and filled his notebooks, but without profit to scholarship. His notes and collations have been used by various editors.
Holstenius died on February 2, 1661.
The principal works that Holstenius actually published are notes on Cluvier's Italia antiqua (1624); an edition of portions of Porphyry (1630), with a dissertation on his life and writings; notes on Eusebius Against Hierocles (1628), on the Sayings of the later Pythagoreans (1638), and the De diis et mundo of the neo-Platonist Sallustius (1638); an edition of Arrian's treatise on the Chase (1644), and the Codex regularum monasticarum, a collection of monastic rules (1661). He also rediscovered and edited for the first time the Liber Diurnus Romanorum Pontificum, a collection of ancient Roman chancery formulae used in the administration of the Roman Church (1660), but this edition, however, was immediately suppressed by Alexander VII.
After his death there were published from his papers collections of synods and ecclesiastical monuments, the Collectio romana bipartita (1662), also the acts of the martyrs Perpetua and Felicitas; Boniface; Tarachus, Probus and Andronicus (1663); Notae et castigationes in Stephan Byzantini ethnica (1684).
