I've been re-watching Derek Jarman's last film "Blue" (1993) this past week.
"In the roaring waters, I hear the voices of dead friends … How did my friends cross the cobalt river, with what did they pay the ferryman? As they set out for the indigo shore under this jet-black sky - some died on their feet with a backward glance. Did they see Death with the hell hounds pulling a dark chariot, bruised blue-black growing dark in the absence of light, did they hear the blast of trumpets?”
"Blue transcends the solemn geography of human limits."
