and spent some time in the school of Salernum, where it is probable
that he enjoyed the instruction of Roger of Parma, Ricardus
Salernitanus, and may have had among his fellow-students Aegidius of
Corbeil. Probably after his return to England he served for a brief
period on the staff of Archbishop Hubert Walter, after whose death
in 1205, but at an unknown period, Gilbert returned once more to the
Continent, where it seems probable he spent the remainder of his life.
This comports best with his extensive European reputation, his surname
"Anglicus" and the comparative dearth in England of any facts relating
to his life. The date of the Compendium I am inclined to place about
1240, prior to the literary activity of Ricardus Parisiensis or
Richard of Wendover, Roland of Parma, Roger Bacon and Theodorius of
Cervia. We may place his death, conjecturally, at about 1250.

The first edition of the Compendium is a small quarto of 362 folios
(724 modern pages), five by seven inches in size, printed in double
narrow columns, in black letter, perfectly legible and clear. The
pagination shows some errors, but the text itself is remarkably
accurate, though the presence of a multiplicity of contractions
and ligatures renders the reading somewhat difficult to the modern
student. On the last page we find the following colophon:

_Explicit compendium medicine Gilberti Anglici correctum et bene
emendatum per dominum Michaelem de Capella artium et medicine
doctorem: ac Lugduni Impressum per Jacobum Saccon: expensis
Vincentii de Portonariis. Anno Domini M.D.x. die vero vigesima mensis
Novembris._
