the oldest part of the city. It is probable that a small settlement, not the city of Kazan, had existed at Zilantaw in the Bulgarian epoch (12th–14th centuries). The nearest settlement, Biş Balta, has been known since Khanate's epoch. In 1560 the Zilantov Monastery of Assumption was established on the hill. In recent centuries, the hill was covered with an old Russian cemetery, attested to since the Khanate's epoch. During the excavations in the 1970s, vestiges of an original monastery were unearthed. The most ancient layer contained indications of a great fire, lending support to the legend about the burning of the snakes. In historians' opinion this great fire would have occurred during the 1223–1236 invasion. Zilantaw actually used to be a high and waterless island, which would make it the best place for snakes to hibernate during winter. The nearest lake was called Zmeinoye or Zmievo, that is, Snake Lake. However, in 1957 Qazansu's course was changed so that the old riverbed, separated from the Kuybyshev Reservoir, was swamped. Nowadays, Zilantaw is an unpractical depressive area, surrounded by plants and depots. The old cloister was reopened here in 2005. Zilant as a state symbol After the conquest of Kazan in 1552, Ivan the Terrible adopted this image with the title of Kazan's khan (tsar). Zilant was also featured in a seal of False Dmitry I as well as a flag of Tsar Alexis. Early Russian images represent Zilant with one head, four chicken legs, a bird's body and a snake tail. This representation is thus a cockatrice rather than a dragon. In 1730 a royal decree established Zilant as a coat of arms of the Kazan Governorate. It was described in the decree as a "black snake, crowned with the gold crown of Kazan, red-winged on the white field". Being the coat of Kazan, Zilant was incorporated into the Russian Imperial coat of arms. The image was added to the arms of all the towns in the governorate. Zilant also appeared on the coat of arms of Kashira, a town located to the south of Moscow, as it was an appendage town of the exiled Kazan khan Ğäbdellatíf back in the 16th century. After 1917, the governorate was abolished and along with it, all the imperial emblems that featured Zilant. Discussion about restoring Zilant as a city symbol resumed in the 1990s. Supporters of Zilant referred to the state
