The names of the six cardinals are given in I diarii di Marino Sanuto Tomo I (Venezia 1879), p. 654: Oliviero Carafa, Jorge da Costa, Giovanni San Giorgio, Antoniotto Pallavicini, Francesco Todeschini-Piccolomini, and Raffaele Riario.
It is frequently stated that Piccolomini was born on 29 May. This is an error. His memorial inscription from St. Peter's Basilica states that he died at the age of 64 years, 5 months, and ten days, which fits with 9 May, but cannot be reconciled with 29 May. The inscription is quoted by Alfonso Chacón (Ciaconius) (1677). Agostino Olduin (ed.).

De Rubeis (Rossi). pp. 213–214.
The earliest biography of Pius III, written by the Vatican Library employee, Onuphrio Panvinio, states that Piccolomini was born on 9 May, not 29 May: "Ipse natus erat vij idus Maij." Bartolomeo Platina; Onuphrio Panvinio (1568). Historia B. Platinae de vitis pontificum Romanorum, a D.N. Jesu Christo usque ad Paulum II. venetum ... (in Latin). Cologne: Maternus Cholinus. p. 364. The same is said by (among others) Alexis Artaud de Montor (1911). The lives and times of the popes. Vol. IV. New York: Catholic Publication Society of America. p. 202.; and by Matteo Sanfilippo (2015), "Pio III, papa."Dizionario Biografico degli Italiani Volume 83 (Treccani 2015).
His appointment was confirmed on 23 April 1463, and he was obligated for annates from 9 January 1462; see: Henry Dubrulle, ed. (1905). Bullaire de la province de Reims sous le pontificat de Pie II (in French). Lille: R. Giard. p. 156, no. 772. Richardson (1998), p. 203, note 49, gives the date 1461. In his Will of 1493, Piccolomini granted the archdiaconate of Brabant a cope worth fifty gold florins de camera.

The papal secretary and client of the della Rovere family, Sigismondo de' Conti, blamed the surgeon, Ludovico Minatensis, and his bad work on the Pope's leg, for Pius' death: "e vita migravit ex ulcere tibiae sinistrae, quod Ludovicus Minatensis imperitus chirugus, sincera etiam parte secata, laethale effecit."

The poisoning is mentioned by Onuphrio Panvinio as a suspicion, Bartolomeo Platina; Onuphrio Panvinio (1568). Historia B. Platinae de vitis pontificum Romanorum. p. 364.: "Pius interim senectae vitiis et mortifero cruris ulcere vehementer affectus, intra sextum et vigesimum pontificatus diem, XV Kalo.

The 16th century Sienese historian Malavolti is more discreet, but still labels the story an opinion: "Fù oppenione di piu persone, che per gelosia havuta da chi governava la Città di Siena, essendo egli di fattion contraria, la morte gli fusse, con danno publoicio, sollecitamente procurata."

The Archbishop of Siena, Antonio Piccolomini, had died on 8 November 1459; Francesco made his arrangements with the Apostolic Camera for his bulls and fees on 6 February 1460: Eubel II, p. 235. Pius II makes clear in his Commentarii that Francesco was only the Administrator.

Francesco was only 21 when he was appointed, which was far below the canonical age for episcopal consecration. Williams, p. 50.
