Opis Chinese mechanical and horological engineering from the Song Dynasty; this diagram provides an overall general view of the inner workings and armillary sphere of Su Song's clocktower built in Kaifeng. The drawn illustration comes from Su Song's book Xin Yi Xiang Fa Yao published in the year 1092. On the right is the upper reservoir tank with the 'constant-level tank' beneath it. In the center foreground is the 'earth horizon' box in which the celestial globe was mounted. Below that are the time keeping shaft and wheels supported by a mortar-shaped end-bearing. Behind this is the main driving wheel with its spokes and scoops. Above that are the left and right upper locks with an upper balancing lever and upper link.

This is a faithful photographic reproduction of a two-dimensional, public domain work of art. The work of art itself is in the public domain for the following reason:
Public domain

Ovo je djelo u javnom vlasništvu u zemlji podrijetla i u drugim zemljama s rokom trajanja autorskih prava za života autora plus 70 godina ili manje.


Morate dodati i oznaku javnog vlasništva za Sjedinjene Američke Države da bi se naznačilo zašto je ovo djelo u javnom vlasništvu u Sjedinjenim Američkim Državama. Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).

The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain".
This photographic reproduction is therefore also considered to be in the public domain in the United States. In other jurisdictions, re-use of this content may be restricted; see Reuse of PD-Art photographs for details.
