over death. Some Christian churches built in the Romanesque and Gothic eras are decorated with swastikas, carrying over earlier Roman designs. Swastikas are prominently displayed in a mosaic in the St. Sophia church of Kyiv, Ukraine dating from the 12th century. They also appear as a repeating ornamental motif on a tomb in the Basilica of St. Ambrose in Milan. A ceiling painted in 1910 in the church of St Laurent in Grenoble has many swastikas. It can be visited today because the church became the archaeological museum of the city. A proposed direct link between it and a swastika floor mosaic in the Cathedral of Our Lady of Amiens, which was built on top of a pagan site at Amiens, France in the 13th century, is considered unlikely. The stole worn by a priest in the 1445 painting of the Seven Sacraments by Rogier van der Weyden presents the swastika form simply as one way of depicting the cross. Swastikas also appear in art and architecture during the Renaissance and Baroque era. The fresco The School of Athens shows an ornament made out of swastikas, and the symbol can also be found on the facade of the Santa Maria della Salute, a Roman Catholic church and minor basilica located at Punta della Dogana in the Dorsoduro sestiere of the city of Venice. In the Polish First Republic the symbol of the swastika was also popular with the nobility. According to chronicles, the Rus' prince Oleg, who in the 9th century attacked Constantinople, nailed his shield (which had a large red swastika painted on it) to the city's gates. Several noble houses, e.g. Boreyko, Borzym, and Radziechowski from Ruthenia, also had swastikas as their coat of arms. The family reached its greatness in the 14th and 15th centuries and its crest can be seen in many heraldry books produced at that time. The swastika was also a heraldic symbol, for example on the Boreyko coat of arms, used by noblemen in Poland and Ukraine. In the 19th century the swastika was one of the Russian Empire's symbols, and was used on coinage as a backdrop to the Russian eagle. Non-Eurasian samples Africa Swastikas can be seen in various African cultures. In Ethiopia the Swastika is carved in the window of the famous 12th-century Biete Maryam, one of the Rock-Hewn Churches, Lalibela. In Ghana, the swastika is among the adinkra symbols
