Ellen Terry. Letter to Sir John Millais. March 30, 1886, writes "Of course I will lend you the dress [presumably the dress worn in the picture, see Ref. Oakley 1981, pp. 183–84, fig. 2] (here it is.) or anything in the world that I possess, that could be of the very smallest service to you".
[F. G. Stephens]. "Fine-Art Gossip." Athenæum no. 3065 (July 24, 1886), p. 122, states that the picture of Portia in the costume of "an Italian advocate" is "not quite finished," and that it is "probably destined for next year's Academy".
[F. G. Stephens]. "Minor Exhibitions." Athenæum no. 3080 (November 6, 1886), p. 606, reviewing the McLean's exhibition, states that Millais's "figure [of Portia] is mainly studied from Miss Mary Anderson" and observes that "she does not look in the least like a Daniel come to judgment".
"Art Note." The Star (September 22, 1887) [p. 2], states that Walter Weblyn bought the picture for 2,000 guineas and intends to include a color reproduction of it in the Christmas number of "The Illustrated Sporting and Dramatic News," of which he is proprietor.

John Guille Millais. The Life and Letters of Sir John Everett Millais. New York, 1899, vol. 2, pp. 192, 483, discusses the selection of "Miss Dolan, a favourite model of Lord Leighton's" as the model for the painting of a Shakespearean heroine; reproduces (opposite p. 192) a three-quarter-length 1886 oil sketch in which the model's pose is nearly identical to that in this picture but in which she wears a Greek dress, and (following p. 196) an 1886 bust of the same model, called Portia, and wearing the high-collared robe.
Ronald Sutherland Gower. Old Diaries, 1881–1901. New York, 1902, p. 48, writes that he saw in Millais's studio on August 2, 1886, "a 'Portia,' in Ellen Terry's red dress in that part, but not a portrait of that actress".
[Roger Fry]. "The Grafton Gallery." Athenæum no. 4048 (May 27, 1905), p. 664, reviewing the exhibition of the Forbes estate at the Grafton Gallery, observes that Portia shows "lamentable" proof "of the destructive effects of popularity".

Malcolm Warner. Letter to Lucy Oakley. June 27, 1977, notes that none of Millais's daughters looked remotely like Portia; suggests that x-rays might reveal the studies Millais's son published in 1899.
Lucy Oakley. "The Evolution of Sir John Everett Millais's Portia." Metropolitan Museum Journal 16 (1981), pp. 181–94, fig. 1, traces the history of the picture from its conception in 1885 as a woman in a Greek dress, probably inspired by the American actress Mary Anderson, to a Shakespearean subject in which the model, presumably Miss Dolan, wears one of Ellen Terry's Portia costumes from the "Merchant of Venice".
