itself a mosque of great architectural merit. In the
center of the whole design the mausoleum occupies a square of 186
feet, with the angles deeply truncated so also form an unequal
octagon. The main feature in this central pile is the great dome,
which swells upward to nearly two-thirds of a sphere and tapers at
its extremity into a pointed spire crowned by a crescent. Beneath
it an enclosure of marble trellis-work surrounds the tomb of the
princess and of her husband, the Emperor. Each corner of the
mausoleum is covered by a similar though much smaller dome erected
on a pediment pierced with graceful Saracenic arches. Light is
admitted into the interior through a double screen of pierced
marble, which tempers the glare of an Indian sky while its whiteness
prevents the mellow effect from degenerating into gloom. The
internal decorations consist of inlaid work in precious stones, such
as agate, jasper, etc., with which every squandril or salient point
in the architecture is richly fretted. Brown and violet marble is
also freely employed in wreaths, scrolls, and lintels to relieve the
monotony of white wall. In regard to color and design, the interior
of the Taj may rank first in the world for purely decorative
workmanship; while the perfect symmetry of its exterior, once seen
can never be forgotten, nor the aerial grace of its domes, rising
like marble bubbles into the clear sky. The Taj represents the most
highly elaborated stage of ornamentation reached by the
Indo-Mohammedan builders, the stage in which the architect ends and
the jeweler begins. In its magnificent gateway the diagonal
ornamentation at the corners, which satisfied the designers of the
gateways of Itimad-ud-doulah and Sikandra mausoleums is superseded
by fine marble cables, in bold twists, strong and handsome. The
triangular insertions of white marble and large flowers have in like
manner given place to fine inlaid work. Firm perpendicular lines in
black marble with well proportioned panels of the same material are
effectively used in the interior of the gateway. On its top the
Hindu brackets and monolithic architraves of Sikandra are replaced
by Moorish carped arches, usually single blocks of red sandstone, in
the Kiosks and pavilions which adorn the roof. From the pillare
