29.--_Chaucer's Puzzle._

[Illustration]

Chaucer himself accompanied the pilgrims. Being a mathematician and a man

of a thoughtful habit, the Host made fun of him, he tells us, saying,

"Thou lookest as thou wouldst find a hare, For ever on the ground I see

thee stare." The poet replied to the request for a tale by launching into

a long-spun-out and ridiculous poem, intended to ridicule the popular

romances of the day, after twenty-two stanzas of which the company

refused to hear any more, and induced him to start another tale in prose.

It is an interesting fact that in the "Parson's Prologue" Chaucer

actually introduces a little astronomical problem. In modern English

this reads somewhat as follows:--

"The sun from the south line was descended so low that it was not to my

sight more than twenty-nine degrees. I calculate that it was four

o'clock, for, assuming my height to be six feet, my shadow was eleven

feet, a little more or less. At the same moment the moon's altitude (she

being in mid-Libra) was steadily increasing as we entered at the west end

of the village." A correspondent has taken the trouble to work this out,

and finds that the local time was 3.58 p.m., correct to a minute, and

that the day of the year was the 22nd or 23rd of April, modern style.

This speaks well for Chaucer's accuracy, for the first line of the Tales

tells us that the pilgrimage was in April--they are supposed to have set

out on 17th April 1387, as stated in No. 23.

Though Chaucer made this little puzzle and recorded it for the interest

of his readers, he did not venture to propound it to his fellow-pilgrims.

The puzzle that he gave them was of a simpler kind altogether: it may be

called a geographical one. "When, in the year 1372, I did go into Italy

as the envoy of our sovereign lord King Edward the Third, and while there

did visit Francesco Petrarch, that learned poet did take me to the top of

a certain mountain in his country. Of a truth, as he did show me, a mug

will hold less liquor at the top of this mountain than in the valley

beneath. Prythee tell me what mountain this may be that has so strange a

property withal." A very elementary knowledge of geography will suffice

for arriving at the correct answer.
