Patientis."

10. "De Re Herbaria."

11. "De Tuenda Valentudine."

12. "De Particularibus Morbis."

13. "Thesaurus Pauperum."

All of these latter may be regarded as doubtful.

The authorities named by Gilbert are Pythagoras, Hippocrates, Plato,
Aristotle, Galen, Rufus, Maerobius, Boetius, Alexander of Tralles,
Theodorus Priscianus, Theophilus Philaretes, Stephanon (of Athens?),
the Arabians Haly Abbas, Rhazes, Isaac Judaeus, Joannitius, Janus
Damascenus, Jacobus Alucindi, Avicenna and Averroes; the Salernian
writers, quoted generally as Salernitani and specifically Constantino
Africanus, Nicholas Praepositus, Romoaldus Ricardus and Maurus, and
two otherwise unknown authors, Torror and Funcius, classed by Gilbert
as "_antiqui_." The latter author is also said to have written a
"_Liber de lapidibus_." Certainly this list suggests a pretty good
medical library for a practitioner of the 13th century.

Dr. Payne calls attention to the fact that all these writers antedate
the 13th century, and thus limit the period of Gilbert in antiquity.
This is undoubtedly true with reference to authorities actually named,
but does not exclude from consideration other writers quoted, but not
named, whom we shall have occasion to refer to hereafter.

The Compendium opens with a very brief and modest foreword, couched in
the following terms:

"_Incipit liber morborum tam universalium quam particularium a
magistro Gilberto anglico editus ab omnibus autoribus et practicis
magistrorum extractus et exceptus, qui compendium medicine
intitulatur._"

It will be observed that no claim whatever for originality is
presented by the author. He calls his book a compendium extracted from
all authors and the practice of the professors, and edited only by
himself. The same idea is more fully emphasized later (f. 55c), where
he says:

"_Sed consuetudo nostra est ex dictis meliorum meliora aggregare, et
ubi dubitatio est, opiniones diversas interserere; ut quisque sibi
eligat quam velit retinere._"

The self-abnegation implied in these extracts must not, however, be
interpreted too literally, for the editorial "_dico_" on numerous
pages, and even an occasional chapter marked "_Propria opinio_,"
testify to the fact that Gilbert had opinions of his own, and was
ready on occasion to furnish them to the profession. On the whole,
however, the "Compendium" is properly classified by the author as a
compilation, rather than an original work.
