The poet Omar Khayyam, in moralizing over the ruins of the fallen splendour of that famous place, speaks in Fitzgerald's 'Rubaiyat': 'They say the lion and the lizard keep The Court where Jamshed gloried and drank deep.' The Persian poet-historian Firdausi ascribes to Jamshed the discovery of wine in his leisure from kingly duties and scientific pursuits, for to him is attributed the invention of many useful arts, and the introduction of the solar year for measurement of time, the first day of which, when the sun enters Aries, he ordered to be celebrated by a splendid festival.

It is called Nauroz, or New Year's Day, and is still the greatest festival in Persia.

This single institution of former days, under a different religion and system of measuring time, has triumphed over the introduction of Mohammedanism, and is observed with as much joy and festivity now as it was by the ancient inhabitants of Persia.
According to Moulla Akbar's manuscripts, quoted in Malcolm's 'History of Persia,' Jamshed was immoderately fond of grapes, and desired to preserve some which were placed in a large vessel and lodged in a vault for future use.

When the vessel was opened, the grapes had fermented, and their juice in this state was so acid that the King believed it must be poisonous.

He had some other vessels filled with the juice, and 'Poison' written upon each; these were placed in his room.
