_Treatise by Englebert, Archbishop of Treves._--Bishop Cosin (in his
_Hist. Trans._ cap. vii. §12) refers to _Engelb. Archiep. Trevirensis,
ap. Goldasti Imper._ tom. i. In Goldast's _Politica Imperialia_ there is
a treatise by S. Engelb. Abb. _Admoutens_ in Austria: but I find neither
the author referred to, nor the treatise intended, by Cosin. According
to Eisengrein, who is followed by Possivinus, there were _two_
Engelberts; viz. Engelbertus, S. Matthiæ _Treverensis_, Benedictinæ
possessionis Abbus, patria _Mosellanus_, who lived A.D. 987; and S.
Engelbert, who flourished A.D. 1157, and who is described as
_Admontensis_ Benedictinæ posessionis Abbus, _Germanus_. Can any of your
correspondents kindly direct me to the intended treatise of the
Archbishop of Treves?
