Taj Mausoleum, Iwan on south, calligraphy: The texts chosen refer broadly to the themes of judgment and fruitful paradisiacal rewards for the faithful. The inscriptions over the gateway invite the reader to enter the paradise. And as one enters towards the main mausoleum, the tone of the inscriptions changes from paradisiacal to that of an impending doom that awaits the unbelievers on the Day of Judgment. However, once inside the mausoleum, the tone of the inscriptions changes yet again from judgment to paradisiacal. The text is written in a language close to the 'Thuluth', a style associated in particular with the Persian calligrapher Amanat Khan who resided at the Mughal court and who was responsible for making the calligraphy of the entire Taj Mahal. His signature appears besides many times in the marble.
