The dome in taj-mahal produces an echo which is more pleasant, pure and lasting than any other.
In his description of the taj-mahal of Agra, that veritable eighth wonder of the world, he calls it "a poem in marble."
mausoleum at Agra, India, built c.1640 by Shah Jahan for his favorite wife, from Persian, literally "the best of buildings;" second element related to Arabic halla "to lodge." But some authorities hold that the name of the mausoleum is a corruption of the name of the woman interred in it, Mumtaz (in Persian, literally "chosen one") Mahal, who died in 1631. Figurative use as a name denoting anything surpassing or excellent is attested from 1895.
