His principal contributions to theological literature were: _Manuductio ad lectionem Scripturae Sacrae_ (1693); _Praelectiones hermeneuticae_ (1717); _Commentatio de scopo librorum Veteris et Novi Testamenti_ (1724); and _Lectiones paraeneticae_ (1726-1736). The _Manuductio_ was translated into English in 1813, under the title _A Guide to the Reading and Study of the Holy Scriptures_. An account of his orphanage, entitled _Segensvolle Fussstapfen_, &c. (1709), which subsequently passed through several editions, has also been partially translated, under the title _The Footsteps of Divine Providence: or, The bountiful Hand of Heaven defraying the Expenses of Faith_. See H. E. F. Guericke's _A. H. Francke_ (1827), which has been translated into English (_The Life of A. H. Francke_, 1837); Gustave Kramer's _Beitraege zur Geschichte A. H. Francke's_ (1861), and _Neue Beitraege_ (1875); A. Stein, _A. H. Francke_ (3rd ed., 1894); article in Herzog-Hauck's _Realencyklopaedie_ (ed. 1899); Knuth, _Die Francke'schen Stiftungen_ (2nd ed., 1903). FRANCKEN. Eleven painters of this family cultivated their art in Antwerp during the 16th and 17th centuries. Several of these were related to each other, whilst many bore the same Christian name in succession. Hence unavoidable confusion in the subsequent classification of paintings not widely differing in style or execution. When Franz Francken the first found a rival in Franz Francken the second, he described himself as the "elder," in contradistinction to his son, who signed himself the "younger." But when Franz the second was threatened with competition from Franz the third, he took the name of "the elder," whilst Franz the third adopted that of Franz "the younger."
