palace to the soldier's tent--following in the equipage of great leading officers, or of subalterns highly connected. There was at that time a practice prevailing, in the great standing camps on the several frontiers and at all the military stations, of renewing as much as possible the image of distant Rome by the erection of long colonnades and piazzas--single, double, or triple; of crypts, or subterranean [Footnote: "_Crypts_"--these, which Spartian, in his life of Hadrian, denominates simply _cryptæ_, are the same which, in the Roman jurisprudence, and in the architectural works of the Romans, yet surviving, are termed _hypogæa deambulationes, i. e._ subterranean parades. Vitruvius treats of this luxurious class of apartments in connection with the Apothecæ, and other repositories or store-rooms, which were also in many cases under ground, for the same reason as our ice-houses, wine-cellars, &c. He (and from him Pliny and Apollonaris Sidonius), calls them _crypto-porticus_ (cloistral colonnades); and Ulpian calls them _refugia_ (sanctuaries, or places of refuge); St. Ambrose notices them under the name of _hypogæa_ and _umbrosa penetralia_, as the resorts of voluptuaries: _Luxuriosorum est_, says he, _hypogæa quærere--captantium frigus æstivum_; and again he speaks of _desidiosi qui ignava sub terris agant otia_.] saloons, (and sometimes subterranean galleries and corridors,) for evading the sultry noontides of July and August; of verdant cloisters or arcades, with roofs high over-arched, constructed entirely out of flexile shrubs, box-myrtle, and others, trained and trimmed in regular forms; besides endless other applications of the _topiary_ [Footnote: "_The topiary art_"--so called, as Salmasius thinks, from _ropæion, a rope_; because the process of construction was conducted chiefly by means of cords and strings. This art was much practised in the 17th century; and Casaubon describes one, which existed in his early days somewhere in the suburbs of Paris, on so elaborate a scale, that it represented Troy besieged, with the two hosts, their several leaders, and all other objects in their full proportion.] art, which in those days (like the needlework of Miss Linwood in ours), though no more than a mechanic craft, in some measure realized the effects of a fine art by the perfect skill of its execution. All these modes of luxury, with a policy that had the more merit as it thwarted his own private inclinations, did Hadrian peremptorily abolish; perhaps, amongst other more obvious purposes, seeking to intercept the earliest buddings of those local attachments which are as injurious to the martial character and the proper pursuits of men whose vocation obliges them to consider themselves eternally under marching orders, as they are propitious to all the best interests of society in connection with the feelings of civic life.
