What was the full name of the person who died on 10 October 1646?  Answer the above question based on the context below:  By the reign of Henry VII the cathedral was complete, appearing much as it does today (though the fittings have changed). From 1508 to 1546, the eminent Italian humanist scholar Polydore Vergil was active as the chapter's representative in London. He donated a set of hangings for the choir of the cathedral. While Wells survived the Dissolution of the Monasteries better than the cathedrals of monastic foundation, the abolition of chantries in 1547 resulted in a reduction in its income. Medieval brasses were sold, and a pulpit was placed in the nave for the first time. Between 1551 and 1568, in two periods as dean, William Turner established a herb garden, which was recreated between 2003 and 2010.Elizabeth I gave the chapter and the Vicars Choral a new charter in 1591, creating a new governing body, consisting of a dean and eight residentiary canons with control over the church estates and authority over its affairs, but no longer entitled to elect the dean (that entitlement thenceforward belonged ultimately to the Crown). The stability brought by the new charter ended with the onset of the Civil War and the execution of Charles I. Local fighting damaged the cathedral's stonework, furniture and windows. The dean, Walter Raleigh, a nephew of the explorer Walter Raleigh, was placed under house arrest after the fall of Bridgwater to the Parliamentarians in 1645, first in the rectory at Chedzoy and then in the deanery at Wells. His jailor, the shoe maker and city constable, David Barrett, caught him writing a letter to his wife. When he refused to surrender it, Barrett ran him through with a sword and he died six weeks later, on 10 October 1646. He was buried in an unmarked grave in the choir before the dean's stall. During the Commonwealth of England under Oliver Cromwell no dean was appointed and the cathedral fell into disrepair. The bishop went into retirement and some of the clerics were reduced to performing menial tasks.

Walter Raleigh
