FURTTENBACH, Joseph (the younger). Feriae Architectonicae, der siebende Theil, das seynd die nur noch übrige Früe und Spattstunden, mit liebreichen Delectationen der drey Arten hochnutzlichen Gebäwen. Oblong 4to. [Ulm, Balthasar Kühn] 1662. Oblong 4to. [24] + 252 + [8]p. Title within typographical border. With 21 engraved plates (20 numbered, extra plate between 14 & 15); five are signed by the author alone, one dated 1649; fifteen are by Joseph Furttenbach the younger, after his father, Joseph Furttenbach, the elder. Contemporary vellum. Architectural treatise from a series entitled Feriae Architectonicae planned in 13 parts; this is number 7 out of a total of nine published (parts 10-13 never appeared in print - see Graesse, below). The present volume was published from Joseph Furttenbach's manuscript by Gabriel Furttenbach; all parts of this series are quite complete and independent in themselves. The work gives directions for conveying information in clear and practical form, with examples from various branches in this field. The specialized areas depicted and described include ship-building (layout of decks and cabins), civic architecture (layout of a town hall), fortification, siege-artillery, gunnery, the construction of ornamental grottoes and shellwork water basins, engineering (pumps & their mechanisms, hoists & pulleys), surveying (mapping, measuring, use of perspective), bookkeeping and setting out records. The sections on military science, contained on pp38-87, comprise descriptions of: a fortress with suggestions for improvements shown in the detailed layout (plate 6) ; the convenient positioning of heavy cannon to ensure firing within effective range ; the construction of defensive bastions; a mobile hod for trapping and containing errant fire bombs (plate 7); the manufacture and use of mortar bombs (plate 8) and of hand-grenades with rules for calculating correct weights; the science of gunnery with details of the precision work entailed in gun sights (plate 9) - here the author makes specific reference to seven of his other works published between 1627 and 1644. Joseph Furttenbach, the younger (1632-55), has used examples of both his own and his father's inventions to illustrate the work; the copper plates are exquisitely executed, some in cross-section, the lettering is neatly calligraphic. The constructions cited, chosen for their demonstration value, show influence of the visit to Italy by the elder Joseph Furttenbach, over some ten years before 1621, after which he returned to Ulm to become the city's chief architect. A good copy of this rare volume in a contemporary binding; some faint marginal browning, a few leaves with light waterstaining in edges of right blank margins. See Graesse II, 648 (parts 1-6 of the series were published 1649-52, within the author's lifetime; he died in 1655); see also Thieme-Becker XII, p606. N° de ref. del artículo 4024
