The room which the Earl of Gowrie entered was a small one of an octagonal shape, having tall lancet windows on every side but one. It had probably, at some period long past, been the interior of one of those small projecting turrets which we still occasionally see ornamenting the angles of the ancient castellated houses of the Italian nobility. The bridge leading towards the Treviso gate, and the small canal were underneath; the city walls rose up black beyond; but the turret was high above, and through the windows, on every side but that next to the city, were seen twinkling the bright and multitudinous stars of heaven. In the centre of the room was a large oaken table bearing a lamp, the flame of which was peculiarly bright and perfectly white in colour, and over the rest of the table were cast in strange confusion a number of curious objects. There were books--some closed, but some open, and displaying characters with which the young earl was perfectly unacquainted. One page was covered all over with cyphers alternately of red and blue; and one was traced with many mathematical figures, which, although the earl was well versed in that science, seemed to him strange and new. Another manuscript lay near, which he saw at once was written in Hebrew, but there were others in which the lines ran from corner to corner of the page, with such a multitude of strokes and flourishes, that the letters themselves could hardly be distinguished. Scientific instruments were there too, tossed about amongst the papers, with the uses of many of which the young lord was unacquainted. There were triangular glasses filled with sand, and glass globes, connected together by a tube of the same substance, half filled with mercury. Squares and triangles of brass covered over with curious signs were there likewise; and round about the room, beneath shelves loaded with ponderous volumes, were several globes, and instruments of a rude construction for observing the stars. In one corner stood a small furnace, with crucibles and retorts, and various other implements of chemical or alchemical science; and on a small pedestal of black marble between two of the windows was raised a crucifix of ebony and ivory, supported by two heads of cherubim, exquisitely sculptured in white marble, the one looking up towards the cross with a bright smile, the other with the eyes bent down, as if weeping, and the whole expression sad. At the foot of the crucifix lay a human skull.
