Origin of Lahore and Etymology of  Lahore

An old street-scene in Lahore.

A mythological legend, based on oral traditions, states that Lahore was named after Lava, son of the Hindu Rama, who supposedly founded the city. To this day, the Lahore Fort has a vacant temple dedicated to Lava (also pronounced Loh, hence "Loh-awar" or The Fort of Loh). Likewise, the Ravi River that flows through northern Lahore was named for the Hindu goddess Durga 
Ptolemy, the celebrated astronomer and geographer, mentions in his Geographia a city called Labokla situated on the route between the Indus River and Palibothra, or Pataliputra (Patna), in a tract of country called Kasperia (Kashmir), described as extending along the rivers Bidastes or Vitasta (Jhelum), Sandabal or Chandra Bhaga (Chenab), and Adris or Iravati (Ravi).
The oldest authentic document about Lahore was written anonymously in 982 and is called Hudu-i-Alam.English by Vladimir Fedorovich Minorsky and published in Lahore in 1927. In this document, Lahore is referred to as a small shahr (City) with "impressive temples, large markets and huge orchards." It refers to "two major markets around which dwellings exist," and it also mentions "the mud walls that enclose these two dwellings to make it one." The original document is currently held in the British Museum.
