This seventh edition of the Periodical Historical Atlas of Europe, available in English and French, was posted on the Web in September 2001. The atlas, a project of Christos Nussli, consists of maps "depicting with accuracy the states of this continent every first day of each centennial year from AD 1 to AD 2000." A legend helps users understand each of the maps, which are presented as expandable thumbnails. The site also links to a bibliography and maps from De Imperatoribus Romanis: An Online Encyclopedia of Roman Emperors. Though the site functions in part as an advertisement for Nussli's CD version of the atlas, it is nonetheless a useful stop in its own right.
