 He was appointed chairman of "The Eglantine" chamber of rhetoric in 1617, shortly after the exit of playwrights Samuel Coster, Pieter Corneliszoon Hooft, and Gerbrand Bredero who formed the competing First Dutch Academy.In support of "The Eglantine", Rodenburgh published the "Eglentiers Poëtens Borst-Weringh", a discussion of poetics based largely on Sir Philip Sidney's "Apologie for Poetrie" and Thomas Wilson's "Arte of Rhetorique", but also influenced by Lope de Vega's "Arte nuevo de hacer comedias en este tiempo" ("New Art of Writing Plays at This Time").The first part of "King Otto III" was published in 1616, and the second and third parts in 1617, but whether it was ever performed is unknown.
