Inis Tuaisceart (Inishtooskert in English) is the northernmost of the Blasket Islands off the tip of the Dingle peninsula. In fact, the name means 'Northern Island', perhaps a little unimaginatively. The official name may be somewhat lacking, but it's known colloquially in Irish as 'an Fear Marbh', or the Dead Man. It does look uncannily like a man lying on his back. Also known in English as 'the Sleeping Giant' or 'the Sleeping Monk'.
Just after taking this picture, I saw a green flash, a second of green light just as the sun dips below the horizon. It's the only time I have seen this optical phenomenon in all my years of photographing sunsets and sunrises.
