Sillig went on to edit many of Böttiger's works after the latter's death in 1835.
[1] He also revised and edited the work of other scholars, such as Christian Gottlob Heyne.
Heyne published an edition of the poem "Culex" from the Appendix Vergiliana, a collection of verse often attributed at least in part to Virgil, and attempted to cull the lines he thought not genuinely produced by Virgil; an approach of which Sillig was highly critical when he revised Heyne's works.
His Catalogus Artificium (1827) was considered a useful work in its time.
He was often referenced in works of 19th century classical scholarship, such as the Dictionary of Greek and Roman Biography and Mythology of William Smith.
