SIMPLE COFFIN Hundreds of well-wishers queued on Thursday and Friday to pay their last respects to Tutu as he lay in state at the cathedral in a simple, closed pine coffin with rope handles, in accordance with his wishes for a frugal funeral. As Anglican archbishop of Cape Town, Tutu turned St George"s into a refuge for anti-apartheid activists during the turbulent 1980s and 1990s when security forces brutally repressed the mass democratic movement. His body will be cremated in a private ceremony after Saturday"s requiem mass and will then be interred behind the pulpit from where he once denounced bigotry and racial tyranny. Church bells have tolled daily this week at St George"s in honour of the man often described as South Africa"s "moral compass". Many would refer to Tutu as "Tata" or father. "Sometimes strident, often tender, never afraid and seldom without humour, Desmond Tutu"s voice will always be the voice of the voiceless," is how long-time friend and former president Nelson Mandela, who died in December 2013, described his friend.
