Eusebius Goff E119; (Boston P.L., Indiana Univ (- 2 ff.) YUL) https://data.cerl.org/istc/ie00119000. This copy contains the fifteen books of the "Praeparatio evangelica," whose purpose is "to justify the Christian in rejecting the religion and philosphy of the Greeks in favor of that of the Hebrews, and then to justify him in not observing the Jewish manner of life [...] "The following summary of its contents is taken from Mr. Gifford's introduction to his translation of the "Praeparitio:

The first three books discuss the threefold system of Pagan Theology: Mythical, Allegorical, and Political.

The next three, IV-VI, give an account of the chief oracles, of the worship of demons, and of the various opinions of Greek Philosophers on the doctrines of Fate and Free Will. Books VII-IX give reasons for preferring the religion of the Hebrews founded chiefly on the testimony of various authors to the excellency of their Scriptures and the truth of their history. In Books X-XII Eusebius argues that the Greeks had borrowed from the older theology and philosphy of the Hebrews, dwelling especially on the supposed dependence of Plato upon Moses. In the the last three books, the comparson of Moses with Plato is continued, and the mutual contradictions of other Greek Philosphers, especially the Peripatetics and Stoics, are exposed and criticized."

The "Praeparitio" is a gigantic feat of erudition, and according to Harnack (Chronologie, II, p. 120), was, like many of Eusebius' other works, actually composed during the stress of the persecution. It ranks, with the Chronicle, second only to the Church History in importance, because of its copious extracts from ancient authors, whose works have perished." (CE)
Eusebius, Greek historian and exegete, Christian polemicist and scholar Biblical canon, became bishop of Cesarea in 314 and is considered as the father of Church History as his writings are very important for the first three centuries of the Christianity.

The Praeparatio consists of fifteen books completely preserved. Eusebius considered it an introduction to Christianity for pagans, but its value for many later readers is more because Eusebius added information from historians and philosophers not recorded elsewhere:

Pyrrho's translation of the Buddhist three marks of existence upon which Pyrrho based Pyrrhonism. During their Indian sojourn with Alexander the Great, Pyrrho and his teacher, Anaxarchus, met Indian gymnosophists, 'naked wise men', and it is said that Pyrrho's philosophy developed as a result of such meetings. When he returned from India, Pyrrho is said to have taught a philosophical ethics, in the sense of how to live the best and happiest kind of life, in terms of the ideals of apatheia, 'being without passion', and ataraxia, 'undisturbedness, calm'.
