The National Gallery in London possesses (No. 748 in the Catalogue) a good example of Girolamo's work, a Madonna altar-piece, signed Hieronymus a libris f. No. 1134 in the same collection is an example of a panel picture by Liberale da Verona. The Bodleian contains an exquisite Book of Hours illuminated by Girolamo dai Libri for the Duke of Urbino.
The Antiphonals which Liberale illuminated at Monte Oliveto are now preserved in the Chapter library at Chiusi. Those which he painted at Siena are now in the Cathedral library. Records of money paid to Liberale for these choir-books are published by Milanesi, Documenti per la Storia dell' Arte Sanese, Vol. II. pp. 384-386; and Milanesi's edition of Vasari, Vol. V. pp. 326-334.
Examples of Attavante's and Liberale's miniatures are illustrated by Eug. Müntz, La Renaissance en Italie et en France, Paris, 1885, p. 188 seq.
See page [200], and compare pages [163] and [175] for examples of similar influence due to the manuscript illuminators of Germany and Italy.
