In this article the author brings together data concerning the printing of one of Hugo Grotius's classical text editions, Lucan's Pharsalia. The first edition was published by Raphelengius in Leiden in 1614. Reissues of this edition saw print in 1626 and 1627, and probably also in 1639. A revised edition was published in 1643 by Blaeu in Amsterdam. The house of Blaeu also brought out two Grotius editions of the Pharsalia in small format in 1619 and 1627; these editions were reprinted in 1626 and 1636 by Blaeu's neighbour Janssonius.
