The legend has it, that Shah Jehan decided to construct another Taj Mahal in black marble on the other side of the river
Yamuna and to connect the two by a bridge. This structure was intended to be his own tomb. It has been recorded by Tavernier : "Shah Jehan began to build his own tomb on the other side of the river but the war with his sons interrupted
his plan and Aurangzeb who reigns at present is not disposed to complete it". Later gazetteers and guide books mention this story almost invariably. The irregular position of the cenotaph of Shah Jehan as compared to that of Mumtaz Mahal which occupies the exact centre of the hall is enough proof into itself.. The Mehtab Burj and the wall adjoining it opposite the Taj Mahal are generally said to be the grim remains of the proposed plan.
Many scholars, however, believe that this idea belongs to fiction rather than history. The traces which are identified as the foundations of the second Taj are actually the enclosing wall of a garden founded by Baber. The irregular position of Shah Jehan''s cenotaph in comparison to Mumtaz Mahal''s, is similar to that at the tomb of Itmad-ud-Daulah, and thus should not be of any striking significance. Besides, according to Islamic law, bodies are buried with their faces towards Mecca and legs towards the south, and the husband is placed on the right hand side of his wife. The interpretation that the cenotaph of Shah Jehan was not meant to be placed here appears to be superfluous.
Till today it is not known who really
designed Taj, but as the rumours say it may
have been designed by an Italian Architect.
Some European scholars held the view that the Taj was designed by an Italian - Geronimo Veroneo. This was first suggested by Father Manrique, an Augustinian Friar, who came to Agra in 1640 A.D. to secure the release of Father Antony who had been imprisoned by the Mughals. It was in Lahore that he met Father Joseph de Castro, the executor of Veroneo who died at Lahore in 1640 A.D., and it was Castro who told him about "the Venetian by the name Geronimo Veroneo who came in the Portuguese ships and died in the city of Lahore before he reached it..."
During the reign of Jehangir, a goldsmith named Veroneo did in fact come to India and, as
mentioned by Father Manrique, did die on his way to Lahore. He lived for a time in Agra, and prospered there. He knew many influential Europeans throughout the North Indian provinces, and when he died, he was buried in the Christian cemetery of Padres Santos in Agra. The theory that Veroneo designed the Taj is intriguing and still finds occasional champions, especially in Italy. But the scales of evidence weigh heavily against it. True there is the testimony of Father
Manrique, but he was no more than a casual tourist who heard that the Taj had been built by an Italian. However, nowhere else is there mentioned that Veroneo participated in planning the Taj Mahal. As a matter of fact, there is no record that Veroneo had any skill other than that of working on gold. Other Europeans who saw the Taj under construction never mentioned his name, and furthermore, it is difficult to suppose that an artist trained in seventeenth century Italy, the Italy of Bernini, could build a mausoleum that would typify Indo-Persian architecture. The Taj is not an isolated phenomenon, the creation of a single mastermind but the glorious consummation of a great epoch of art.
The Basement Chambers and a probable Third Grave Two staircases on the northern side of the red sandstone plinth of the Taj lead below into the basement chambers which are seventeen in number and have been laid out in a line on the riverside of a narrow through-corridor. The rooms and corridor are of acurate construction in brick and plaster, with stucco and painting ornamentation, distributed aesthetically on the soffits. At the
extreme points on both sides there doors sunk in the northern wall. They were blocked up permanently and securely with thick masonry at some unknown date, undoubtedly for some well calculated purpose. As may be surmised, the set on the northern side could have been repeated on the sides below the marble structure, with a rotating corridor, chambers and probably a crypt in the centre - all being interconnected.
