This 15th-century doodle is found in the lower margin of a manuscript containing Juvenal’s Satires. This classical text was a popular device to teach young students – kids – morals. The medieval teacher Alexander Nequam stated: “Let the student read the satirists […] so that he may learn even in his younger days that vices are to be shunned” (quote here). Spoken like a true optimist, because this page shows what young school boys like to do with rules: disobey them. And so in stead of studying the student who used this book drew a funny doodle in the lower margin: a figure with a flower in one hand and what appears to be a pipe in the other. Could it be his teacher? Doodles are of all ages but those produced by bored school kids are the most entertaining.
