308 AsTER History ; THE AGGREGATOR 
Date.—The Aggregator cites only 15 authors, as its Avicenna, 
Mesue, Averroes; and its ‘ Diascorides,’’ known to its author 
chiefly if not wholly through Serapion. The latest authors cited 
are its ‘‘ Bartholomaeus Anglicus,’ circa 1256, its ‘ Pandecta,” 
by 1317, and its “ Albertus de virtutibus,’ the Pseudo-Albertus or 
Albertus de Saxonia, who may have written about 1300. The

been exhibited in N. Y. in 1901 as of Arnoldi de Novavilla, and another in 1902. 
The ascription to hewia arose from the ornamented first page of the Vicenza edi- 
tion of 1491, which was embellished with two figures of philosophers discussing 
herbs, under which their names were printed as Arnoldi de Nova Villa and Avicenna. 
The 1499 edition omitted the figures but repeated the names ; thus beginning by seeming 
to declare itself (and so Hain [no. 1807] recorded it) as ‘*the Avicenna of Arn oldus 
de Nova Villa.’’ Gesner in 1552 observed that it certainly was not by Amald, and 
Meyer in 1857 called attention to the fact that its author expressly mentions Arnald 
and Avicenna in his preface as men of a pas
