The blogger at Summa Minutiae has begun to memorize the Psalms. He has the first two psalms committed to memory!
I'm trying to memorize Psalm 51 in the Coverdale version. My modest goal is the first seven verses by the day after tomorrow.
If I succeed with this psalm, I may try a few of the shorter psalms.
I used to memorize things with great facility -- the poetry of Dylan Thomas and E E Cummings, most notably -- but now the mind's powers grow feeble, I fear.
