The Editio Princeps of the complete extant works of Basil in the original Greek is that which Froben published for Janus Cornarius at Bale in 1551.  But Froben had already published in 1532, under the editorship of Erasmus, an edition containing the De Spiritu Sancto, the Hexæmeron, the Homilies on the Psalms, twenty-nine different Homilies and some Letters.
