These tumuli are found existing in immense numbers in every necropolis of the Etruscans. A large space was generally set apart for the purpose outside the walls of all their great cities. In these cemeteries the tumuli are arranged in rows, like houses in streets. Even now we can count them by hundreds, and in the neighbourhood of the largest cities—at Vulci, for instance—almost by thousands. Most of them are now worn down by the effect of time to nearly the level of the ground, though some of the larger ones still retain an imposing appearance. Nearly all have been rifled at some early period, though the treasures still discovered almost daily in some places show how vast their extent was, and how much even now remains to be done before this vast mine of antiquity can be said to be exhausted. One of the most remarkable among those that have been opened in modern times is at Cervetri, the ancient Cære, known as the Regulini Galeassi tomb, from the names of its discoverers. [Illustration: 171. Sections of the Regulini Galeassi Tomb. (From Canina’s ‘Etruria Antica.’) Scale for large section, 50 ft. to 1 in.] Like a Nubian pyramid or Buddhist tope, it consists of an inner and older tumulus, around and over which another has been added. In the outer mound are five tombs either of dependent or inferior personages. These were rifled long ago; but the outer pyramid having effectually concealed the entrance to the principal tomb, it remained untouched till very lately, when it yielded to its discoverers a richer collection of ornaments and utensils in gold and bronze than has ever been found in one place before. The dimensions and arrangements of this tumulus will be understood from Woodcuts Nos. 170, 171, and from the two sections of the principal tomb which are annexed to them. These last display an irregularity of construction very unusual in such cases, for which no cause can be assigned. The usual section is perfectly regular, as in the annexed woodcut (No. 172), taken from another tomb at the same place. These chambers, like all those of the early Etruscans, are vaulted on the horizontal principle, like the tombs at Mycenæ and Orchomenos, though none are found in Italy at all equal to those of Greece in dimensions or beauty of construction. [Illustration: 172. Section of a Tomb at Cervetri. No scale.] Woodcut No. 173 is a perspective view of the principal chamber in the Regulini Galeassi tomb, showing the position of the furniture found in it when first opened, consisting of biers or bedsteads, shields, arrows, and vessels of various sorts. A number of vases are hung in a curious recess in the roof, the form of which would be inexplicable but for the utensils found in it. With this clue to its meaning we can scarcely doubt that it represents a place for hanging such vessels in the houses of the living.
