In the middle age of Italy, the houses had almost always three rooms: _domus_ (kitchen), _thalamus_, _solarium_. (_Cibrario_, E. P. del medio Evo, III, 45.) The manors or masters' houses built on the estates of Charlemagne had 3 and 2 rooms, sometimes only 1, and sometimes 2 rooms and 2 bedrooms. According to an old document of 895, a shed was worth 5 sols, a well-built manor 12. (_Anthon_, Geschichte der deutschen Landwirth., I, 249 ff., 311.) The Lex Alamanorum, tit. 92, provided that a child, in order to be considered capable of living, should have seen the roof and four walls of the house! See an able essay, capable of being still further developed, by _E. Herrmann,_ in which he endeavors to explain the _division of use_ and of labor on Darwin's hypothesis of the origin of species in the D. Vierteljahrsschrift, Januar., 1867.] [Footnote 207-5: Thus, 1785-1795, the best Silesian wool cost 60, the worst 26, thalers per cwt.; in 1805, on account of the great demand for cloth to make military uniforms, the former cost 78, the latter 50 thalers. (_Hoffmann_, Nachlass, 114.)] [Footnote 207-6: The one large kitchen naturally requires much less place, masonry, fuel, fewer utensils, etc., than 100 small ones. Think of the relatively large savings effected by the use of one oven kept always heated! Even the Lacedemonians called their meal associations φειδίτια, i. e., save-meals. Dainties proper can be consumed only in very small portions, but cannot well be prepared in such quantities. A guest at a first class Parisian restaurant has, at a moderate price, his choice of 12 _potâges_, _24 hors d'œuvres_, _15-20 entrées de bœuf_, _20 entrées de mouton_, _30 entrées de volaille et gibier_, _15-20 entrées de veau_, _12 de pâtisserie_, _24 de poisson_, _15 de rôts_, _50 entremets_, _50 desserts_; and, in addition, perhaps 60 kinds of French wine alone. What more can a princely table offer in this respect? Compare _Brillat-Savarin_, Physiologie du Goût, Médit., 28.] [Footnote 207-7: In Diocletian's time, there was purple silk worth from 2½ thalers to 250 thalers per pound. (_Marquardt_, Röm. Privatalterthümer, II, 122.)]
