Steinmann, Ghirlandaio, Leipzig, 1897, pp. 18-21, and pl. 10 and 13, who recognizes, among the members of the Florentine colony in Rome, Argyropoulos and Giovanni Tornabuoni. 88. See Steinmann, op. tit., p. 40 ff.
^Burnell, Frederic Spencer. Rome. Longmans, Green & co. 1930: 217. OCLC 7141638. We may perhaps recognize, in the group on the right, the bearded head of the famous Greek scholar, Argyropoulos, and, immediately to the left, the wealthy banker, Giovanni Tornabuoni
^Marle, Raimond van; Marle, Charlotte van. The development of the Italian schools of painting, Volume 13. M. Nijhoff. 1923: 30. OCLC 162830458. Among the portraits Herr Steinmann has succeeded in recognizing the Greek, Jean Argyropoulos, commentator of Aristotle, who is the old man with a long beard, the papal treasurer, Giovanni Tornabuoni ... he is the clean-shaven man to the right of Argyropoulos while the oldest of the three boys might be Lorenzo, the son of Giovanni Tornabuoni.
^Davies, Gerald Stanley. Ghirlandaio. Methuen and co. 1909: 53. OCLC 192133437. Next to him a greybearded man with a flat hat, seen only head and shoulders, is with tolerable certainty recognised as the Greek humanist, Johannes Argyropulos, the translator into Italian of Aristotle. He had been invited by Cosimo dei Medici
