From a reader from back on 11/11/11:
I thought that you and your readers might find this legend of Satan, St. Martin of Tours, and two exquisitely long palindromes, to be of interest particularly on this palindromic day of 11/11/11.
From The Book of Days, Vol. II, R. Chambers, ed., W. & R. Chambers, Ltd., London & Edinburgh, 1864, p. 568:
“Martin, having occasion to visit Rome, set out to perform the journey thither on foot. Satan, meeting him on the way, taunted the holy man for not using a conveyance more suitable to a bishop. In an instant the saint changed the Old Serpent into a mule, and jumping on its back, trotted comfortably along. Whenever the transformed demon slackened pace, Martin, by making the sign of the cross, urged it to full speed. At last, Satan, utterly defeated, exclaimed:
‘Signa te signa: temere me tangis et angis:
Roma tibi subito motibus ibit amor.’
