 Pope Sylvester I (285 – 31 December 335) was the bishop of Rome from 31 January 314 until his death.He filled the see of Rome at an important era in the history of the Western Church, yet very little is known of him. <br />
<br />
In the West, the liturgical feast of Saint Sylvester is on 31 December, the day of his burial in the Catacomb of Priscilla.[6] This is now the last day in the year and, accordingly, in German-speaking countries and in some others close to them, New Year's Eve is known as Silvester. In some other countries, too, the day is usually referred to as Saint Sylvester's Day or the Feast of Saint Sylvester.<br />

The stained glass windows of Chartres Cathedral are held to be one of the best-preserved and most complete set of medieval stained glass, notably celebrated for their colours, especially their cobalt blue. They cover 2600 square metres in total and consist of 172 bays illustrating biblical scenes, the lives of the saints and scenes from the life of trade guilds of the period
