The Ural pictograms (Russian: уральские писаницы) are prehistoric pictograms in Ural dated to 3,000–2,000 years BC[1] and located along the coasts of Tagil River, Neyva River, Rezh River, Yurozan River and some other sites. The color of the pictograms is different, varying from ochre, probably mixed up with blood, to lilac and brown, while the thickness is between 10 and 20 mm. The existence of the Ural characters was known long ago. Peter the Great in 1699 ordered the scrivener Yakov Losyov to go there and make an exact copy.[1]
The Ural pictograms span for about 800 km from north to south. The northernmost ones were found on the rivers Kolva and Vishera, while the southernmost ones were detected at Belaya River. The majority of Ural pictograms, however, were discovered along the Tagil River.
The Ural pictograms are tied to the indigenous Ural population.[2] The pictograms were painted by finger or some tool from the ground level and artificial elevations, which allowed painting at the height of over three meters.[2] Some pictogram lines are 4-5 cm thick. The images are generally aligned to the south. The Ural pictograms include the images of birds, animals, humans and various geometrical figures. The images of animals mainly depict moose, deer and roe deer. The birds are generally represented by waterfowl, mainly ducks and geese. Other images depict snakes and bear. Several pictograms of living beings feature skeleton pattern, showing the internal organs.[citation needed]
In 2001 a carved image was found at the River Rezh, which disproved the long-standing opinion that all Ural pictograms are painted.[3]
According to Russian researcher Valeriy Chernetsov, who published The Rock Images of Ural (1st volume in 1964, 2nd volume in 1971), the Ural pictograms generally depict the hunting utensil.[1] The pictograms, however, as emphasized by Chernetsov, have no direct association with fishing as no images of fishes have been found on sites.[1]

A pictogram (also pictogramme, pictograph, or simply picto) is a graphic symbol that conveys meaning through its visual resemblance to a physical object. Pictograms are used in systems of writing and visual communication. A pictography is a writing system which uses pictograms. Some pictograms, such as hazard pictograms, may be elements of formal languages. In the field of prehistoric art, the term "pictograph" has a different definition, and specifically refers to art painted on rock surfaces. Pictographs are contrasted with petroglyphs, which are carved or incised. Small pictograms displayed on a computer screen in order to help the user navigate are called icons.

The DOT pictograms are a set of fifty pictograms used to convey information useful to travelers without using words. Such images are often used in airports, train stations, hotels, and other public places for foreign tourists, as well as being easier to identify than strings of text. Among these pictograms are graphics representing toilets and telephones. As a result of their near-universal acceptance, some describe them as the "Helvetica" of pictograms, and the character portrayed within them as “Helvetica Man.” As works of the United States government, the images are in the public domain and thus can be used by anyone for any purpose, without licensing issues.
Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Two sets of pictograms are included within the GHS: one for the labelling of containers and for workplace hazard warnings, and a second for use during the transport of dangerous goods. Either one or the other is chosen, depending on the target audience, but the two are not used together for the same hazard. The two sets of pictograms use the same symbols for the same hazards, although certain symbols are not required for transport pictograms. Transport pictograms come in a wider variety of colors and may contain additional information such as a subcategory number. Hazard pictograms are one of the key elements for the labelling of containers under the GHS, along with: an identification of the product; a signal word – either Danger or Warning – where necessary hazard statements, indicating the nature and degree of the risks posed by the product precautionary statements, indicating how the product should be handled to minimize risks to the user (as well as to other people and the general environment) the identity of the supplier (who might be a manufacturer or importer) The GHS chemical hazard pictograms are intended to provide the basis for or to replace national systems of hazard pictograms. It has still to be implemented by the European Union (CLP regulation) in 2009. The GHS transport pictograms are the same as those recommended in the UN Recommendations on the Transport of Dangerous Goods, widely implemented in national regulations such as the U.S. Federal Hazardous Materials Transportation Act (49 U.S.C. 5101–5128) and D.O.T. regulations at 49 C.F.R. 100–185.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
