Bellerophon transforms your mild-mannered iPhone or iPad into a bastion of scholarship. Browse a compendious library comprising thousands of texts ranging from Homer to Ammianus Marcellinus to Beowulf and spanning millennia, compare multiple works side-by-side, add your own notes and bookmarks for quick reference, view morphological analyses for Greek and Latin texts, and more! Bellerophon includes the following features: * Over 3,500 texts in 10 languages included, with no internet access needed! * Includes texts ranging from canonical classical works to lesser-known authors like Quintus Smyrnaeus and Anna Komnena, to works outside the traditional sphere of classics such as Beowulf, ancient Jewish and biblical texts, and much more! Most texts are in the original language, but the collection also includes over 900 translations into English, as well as some surprising versions of familiar works (such as Aristotle's Poetics in Arabic). * For Greek and Latin, you can request morphological analyses from the Perseus Digital Library by double-tapping on a word (note that this does require an internet connection). * Quickly navigate any text via a hierarchical table of contents, add your own bookmarks for even faster reference to specific sections, or just jump straight to a particular passage by entering it in citation form. * Search the full text of any document, matching on a specific word or substring, and page through results. * Open multiple windows side-by-side in the same session: you can compare the different passages of the same text, view the original alongside a translation, or juxtapose entirely separate texts. * Add your own notes to record new vocabulary or whatever else you like. Additionally, many texts include the contents of footnotes originally present in the printed editions, ranging from apparatus criticus entries to helpful background information.
