They wrote commentaries on classical or medieval some of Leoniceno’s complaints were due to a faulty text texts and compiled encyclopedias that were comparable to of Pliny’s Naturalis historia (Thorndike 1934: Chapter 66). those by Albertus Magnus (c.1220–1280) (see Egerton Meanwhile, Venetian scholar-diplomat Ermolao Barbaro [2003] A History of the Ecological Sciences, Part 9 ), with the (1454–1493) studied copyists and printers’ errors in Pliny’s added advantage that theirs were usually published when Naturalis historia and claimed to find 5000 in two pub- written.

Previously, Niccolò Perotto had published Commentariolus in prooemium Plinii (c.1480) to complain about printer’s errors in Giovanni Andrea de’ Bussi’s edi- tion of Pliny (Nauert 1979:77), and Marc’ Antonio Sabellico had also published about a hundred corrections in his Emen- dationes in Plinium (1488) (Branca 1973:223). Barbaro’s more ambitious Castigationes Plinianae appeared in two parts in 1492–1493. Both Leoniceno and Collenuccio claimed to find support for their case in Barbaro’s work, but Barbaro’s own sympathy was clearly with Collenuccio, since he criticized Leoniceno without naming him (Greene 1983: Chapter 13, French 1986). Other scholars weighed into this debate on one side or the other, and it might have been considered a draw except that in one sense Leoniceno won, because he continued attacking Pliny in print after both Barbaro and Collenuccio had died (Castiglioni 1953, 274– 275). He also was vindicated by being succeeded at Ferrara by one of his pupils, Manardo, an outstanding physician whose botanical expertise is discussed below. During this time in Italy, professionals began testing classical and medieval authorities against nature. Physicians and artists led the way. Medical schools had been dissect- ing executed criminals since the late 1300s, and artists be- gan studying animal and human anatomy. Leonardo da Vinci (1452–1519) is the most famous example. He made Fig. 1. Otto Brunfels. July 2003 131 that occur within a single species growing in differing loca- tions” (Cotton 1974:75). The other student was a German scholar, Euricius Cordus (1486–1535), who received his doctorate under Leoniceno in 1522, when the latter was 94 years old; it seems likely that Manardo was already de facto professor by then. Perhaps Cordus learned, or at least polished, his Greek under Leoniceno, for in 1532 he published a Latin translation of two ancient Greek pharma- ceutical poems. However, Cordus is remembered for his colloquy, Botanologicon (1534), which attempted to cor- rect the mismatch between the names of plants used by Dioscorides and Galen and the actual plants of Germany. Brunfels, for example, while rendering valuable service by publishing his illustrated herbal, had nevertheless mis- matched some classical names with his illustrations, one being a picture of Corydalis to illustrate a classical ac- count of Aristolochia (Cordus 1534:96).
