Scholars, students, and educators of Dante's Divine Comedy, as well as aficionados of the medieval poet's masterpiece, may find Dante Lab to be of interest. First launched in 2013, Dante Lab is a project of Dartmouth College that grew out of its predecessor, the Dartmouth Dante Project (DDP). The DDP "edited and digitized the entire texts of more than 75 commentaries to the Divine Comedy," written between the 14th century and the 21st century. As a follow-up to the DDP, Dante Lab offers an innovative web application that enables its visitors "to read and compare up to four texts from the site's database simultaneously." In addition to the previously digitized commentaries, Dante Lab's database includes the full texts of Giorgio Petrocchi's critical edition in Italian (upon which all modern translations are based), Longfellow's 1867 English translation, Streckfuss's 1854 German translation, and Cioranescu's 1964 French translation. New users should begin by visiting the Help section, where they will find tutorials on using, customizing, and citing the Reader. This section also offers several suggestions of Teaching Scenarios for students and scholars at various levels which may be helpful to educators interested in using Dante Lab with their students.
