at Payne's sale April 7, 1789, for L4.4s. The binder,
possibly mistaking the date of the author's subscription (Vienna, 1444)
for that of the printing, has placed it on the back of the volume. Leaf
7-3/4 x 5-1/4 in.

20. PIUS II. (AENEAS SILVIUS PICCOLOMINI). De curialium miseria. [Paris,
Michael Friburger, Ulric Gering and Martin Crantz, 1472.]

_Fol. 1^a_: Aeneae Siluii poaetae laureati (cui _et_ pro pontificali
dignitate Pio nomen est) in disputatione_m_ de curialiu_m_ miseria ad
perspicacissimu_m_ iurisconsultu_m_ Iohanne_m_ Ech, serenissimi
diuiq_ue_ principis, Alberti, caesaris inuictissimi! Alberti quoque
austriae ducies inclyti consiliariu_m_ atq_ue_ oratore_m_ praefacio
f[oe]liciter incipit; _Fol. 34^a_: Vale uir (nisi ex curialibus unus
esses) meo iudicio prudens; COLOPHON: Aeneae Siluii de curialiu_m_
miseria disputatio finem habet f[oe]licem; _Fol. 35, 36, blank._

Quarto. Quires [1-3^{10}, 4^6], 36 leaves, the last two blank, 23
lines to the page, roman letter, without signatures, catchwords,
pagination, place, printer's name or date. Two- and six-line spaces
left for capitals. Claudin XX. Pellechet 132. Hain 198.

First initial rubricated in the same style and by the same hand as in
the _De duobus amantibus_. Other capitals and paragraph-marks in red and
blue alternately. Initial-strokes in yellow. At the bottom of fol. 29^a
a line accidentally dropped by the compositor is supplied in manuscript
by a contemporary hand, viz., "non te uolunt. Quida_m_ uero pote_n_tes
sunt! ac ex." Both the recto and the verso of the leaf have the full
complement of 23 lines but there is a hiatus in the text. The copies in
the Bibliotheque Nationale, and the Bibliotheque Mazarine, Paris, have
the line supplied in manuscript in like manner, but instead of _uero_
read _non_, which does not suit the context.

According to Claudin this is the twentieth book printed at the Sorbonne
press. To the five copies known to him this adds a sixth.

Bound with No. 19. De duobus amantibus.

21. PLATO. Epistolae. [Paris, Michael Friburger, Ulric Gering and Martin
Crantz, 1472.]
