Input: Question: Who is Thomas Becket? Passage:The University of Kent's coat of arms was granted by the College of Arms in September 1967. The white horse of Kent is taken from the arms of the County of Kent (and can also be seen on the Flag of Kent). The three Cornish choughs, originally belonging to the arms of Thomas Becket, were taken from the arms of the City of Canterbury. The Crest depicts the West Gate of Canterbury with a symbolic flow of water, presumably the Great Stour, below it. Two golden Bishops' Crosiers in the shape of a St. Andrews Cross are shown in front of it. The supporters – lions with the sterns of golden ships – are taken from the arms of the Cinque Ports.
