Note 851 — Chapter XLVIII
Reading edition
Brown (1897), pp. 19-20, 36-7. But not much reliance can be placed on the inclusion of this name, “Master Philip of Tripoli,” in a title which Brown (p. 20) quotes from a De Rossi MS, “The Book of the Inspections of Urine according to the opinion of the Masters, Peter of Berenico, Constantine Damascenus, and Julius of Salerno; which was composed by command of the Emperor Frederick, Anno Domini 1212, in the month of February, and was revised by Master Philip of Tripoli and Master Gerard of Cremona at the orders of the King of Spain,” etc., since Gerard of Cremona at least had died in 1187 and there was no “king of Spain” until 1479. Brown does not give the Latin for the passage, but if the date 1212 could be regarded as Spanish era and turned into 1174 A. D., Gerard of Cremona would still be living, the emperor would be Frederick Barbarossa instead of Frederick II, and Master Philip of Tripoli might be the same Philip whom Pope Alexander III proposed to send to Prester John in 1177.
Steele (1920) p. xix, inclines to identify Philip of Tripoli with a canon of Byblos from 1243 to 1248, but that seems to me too late a date for his translation of The Secret of Secrets.
