[2980] He calls himself, “iohannes quidam agarenus (Saracenus?) quondam, qui noviter ad fidem christiane religionis venerat cum rustico pisano belle filius ac professione medicus.”
[2981] The main objection to this theory is that Stephen of Pisa, translating in 1127, speaks as if the latter portion of Ali’s work was still untranslated. Rose therefore holds that John had not yet published his translation, although we have seen that he completed the surgical section by 1115.
[2982] In Opera omnia ysaac, Lyons, 1515, II, fols. 144-72, “Viaticum ysaac quod constantinus sibi attribuit”; in the Basel, 1536, edition of the works of Constantinus, pp. 1-167, under the title, “De morborum cognitione et curatione lib. vii”; in the Venice, 1505, edition of Gerardus de Solo (Bituricensis), “Commentum eiusdem super viatico cum textu”; and in the Lyons, 1511, edition of Rhazes, Opera parva Albubetri.
A fairly early but imperfect MS is CU Trinity 1064, 12-13th century.
Laud. Misc. 567, late 12th century, fol. 2, recognizes in its Titulus that the Viaticum is a translation, “Incipit Viaticum a Constantino in Latinam linguam translatam.”

[2985] In the 1515 edition of Isaac’s works, I, 11-, 156-, and 203-. Peter the Deacon presumably refers to these three works in speaking of “Dietam ciborum. Librum febrium quem de Arabica lingua transtulit. Librum de urinis.” Whether the two initial treatises in the 1515 edition of Isaac, dealing with definitions and the elements, were translated by Constantinus or by Gerard of Cremona is doubtful.
