But when I was in graduate school, I first encountered the fun of acrostics. In the high Middle Ages, scholars like Alcuin of York (Charlemagne's tutor) used to write short poems that contained clever messages--sometimes hidden--when read a certain way. In their simplest form, the first letter of each line would be carefully selected so that, when read down, the reader could discern a message. However, they could be more complex as well, which always fascinated me.
I just knew that I had to work acrostics and other puzzles into my story, when I came across this acrostic published just after the Great Fire of London in 1666:
Lo! Now confused Heaps only stand
On what did bear the Glory of the Land.
No stately places, no Edefices,
Do now appear: No, here’s now none of these,
Oh Cruel Fates! Can ye be so unkind?
