Fragments of a work on legal boundaries attributed to him will be found in C. F. Lachmann, Gromatici Veteres, i (1848) and in Carl Olof Thulin, Corpus agrimensorum Romanorum, I Opuscula agrimensorum veterum, Leipzig 1913. The "surname" Gromaticus was falsely attributed to Hyginus: There is only one reading in the manuscripts (Arcerianus A 161) which ascribes the work to a KYGYNVS GROMATICVS. The other mss. give the work the title LIBER HYGINI GROMATICVS, so undoubtedly the book was called Liber gromaticus. A treatise on Roman military camps (De Munitionibus Castrorum), was formerly attributed to him, but is probably of later date, about the 3rd century AD (ed West Gemoll, 1879.
A von Domaszewski, 1887) and is now attributed to "Pseudo-Hyginus".
