to the verbal description, and as memoranda of the compositions.
The Cyclopedia being intended primarily for English readers, each painter is treated under his best-known English appellation, whether surname, assumed name, or sobriquet. Thus, Correggio will be found under that title, and not under his less-known family name of Allegri; and, in like manner, Domenichino will be used instead of Zampieri, Giorgione instead of Barbarelli, Pinturicchio instead of Biagi, Raphael instead of Sanzio, Tintoretto instead of Robusti, Titian instead of Vecelli, etc.
The work is under obligations to Mr. Louis von Eltz for his efficient labors during its entire progress, and especially for his valuable aid in researches connected with the German, Flemish, Dutch, and Scandinavian schools of painters.
Thanks are due, also, to the superintendent and other officials of the Astor Library for numerous privileges and courtesies, without which the work on the Cyclopedia would have been attended with great difficulties, if not rendered impossible.
