Across from our hotel was Jantar Mantar, a fascinating group of red structures that were built as instruments for measuring time.
Functions: Measuring the altitude of the sun, measuring time in hours, and measuring the longitude of the moon and measures to the nearest minute of an arc.
Function: Measures local time, much like a sundial.
Function: Measures horizontal and vertical angles of the sun and moon.
After our visit to Jantar Mantar we went to see the Qutb Minar complex. At the Qutb complex there were amazing archways full of calligraphic inscriptions and patterns. Some of the pillars holding up the surrounding structures had traces of Hindu gods and goddesses left over from before their disfiguration. (Islamic art and structures are not allowed to depict human or animal figures.)
Calligraphic inscriptions excerpted from the Quran.
Calligraphic details on the archway are excerpts from the Quran.
