which year artists start painting daily objects instead of royal ppl alone?

Answer 1

um when man first walked the earth (hello cave paintings of hunts)

Answer 2

A lot of ancient cultures have paintings of "normal" objects. I know of a roman fresco of a bowl of fruit and pigeons. These scene are called "stillife" as they depict something "dead" like fruit of flowers. Sometimes there are however living things in them like animals. (Before that period I know of some ancient Greek pots from the "orientalist" period that show animals.)

If you are looking for an answer regarding the middle ages, the artist Hieronumys Bosch (Dutch) made some paintings of peasants and other people at their daily work. These were not meant as personal portraits.

In the Renaissance also non-royals were making a lot of money by trading goods. They were sometimes more influentual than the royals because of their money. These merchants ordered portraits and paintings with stillife that often had hidden meanings. Sometimes allegories or verses were inculded.

The Dutch seventheenth century was special because there were no catholics or royals to order paintings. People were protestant and the money lay with the merchants again. The ordered portraits of themselfs and family, stillifes and allegories ("genre")

So you see, Many periods have used "daily objects" in their paintings...
Good luck.

Answer 3

The interest on looking at everyday objects and trying to represent them in a 'Natural' way began in the late 19th century with the Naturalists. A movement that contrasted with the fashionable Romanticism in which stylising, glorifying or dramatizing their subject is part of it's aesthetic characteristics .

Naturalists worked outside directly with their subject matter and were interested on nature.
