Most people’s to-do lists are, almost by defÂiÂnÂiÂtion, pretÂty dull, filled with those quoÂtidÂiÂan litÂtle tasks that tend to slip out of our minds. Pick up the launÂdry. Get that thing for the kid. Buy milk, canned yams and kumquats at the local marÂket.
LeonarÂdo Da VinÂci was, howÂevÂer, no ordiÂnary perÂson. And his to-do lists were anyÂthing but dull.
Da VinÂci would carÂry around a noteÂbook, where he would write and draw anyÂthing that moved him. “It is useÂful,” LeonarÂdo once wrote, to “conÂstantÂly observe, note, and conÂsidÂer.” Buried in one of these books, datÂing back to around the 1490s, is a to-do list. And what a to-do list.
NPR’s Robert KrulÂwich had it directÂly transÂlatÂed. And while all of the list might not be immeÂdiÂateÂly clear, rememÂber that Da VinÂci nevÂer intendÂed for it to be read by web surfers 500 years in the future.
[CalÂcuÂlate] the meaÂsureÂment of Milan and SubÂurbs
[Find] a book that treats of Milan and its churchÂes, which is to be had at the stationer’s on the way to CorÂduÂsio
[DisÂcovÂer] the meaÂsureÂment of Corte VecÂchio (the courtÂyard in the duke’s palace).
[DisÂcovÂer] the meaÂsureÂment of the castelÂlo (the duke’s palace itself)
Get the masÂter of arithÂmetic to show you how to square a triÂanÂgle.
Get MessÂer Fazio (a proÂfesÂsor of medÂiÂcine and law in Pavia) to show you about proÂporÂtion.
Get the Brera FriÂar (at the BeneÂdicÂtine Monastery to Milan) to show you De PonÂderibus (a medieval text on mechanÂics)
[Talk to] GianÂniÂno, the BomÂbardier, re. the means by which the towÂer of FerÂrara is walled withÂout loopÂholes (no one realÂly knows what Da VinÂci meant by this)
Ask BenedetÂto PotiÂnari (A FloÂrenÂtine MerÂchant) by what means they go on ice in FlanÂders
Draw Milan
Ask MaeÂstro AntoÂnio how morÂtars are posiÂtioned on basÂtions by day or night.
[ExamÂine] the CrossÂbow of MasÂtro GianÂnetÂto
Find a masÂter of hydraulics and get him to tell you how to repair a lock, canal and mill in the LomÂbard manÂner
[Ask about] the meaÂsureÂment of the sun promised me by MaeÂstro GioÂvanÂni Francese
Try to get Vitolone (the medieval author of a text on optics), which is in the Library at Pavia, which deals with the mathÂeÂmatÂic.
You can just feel Da Vinci’s voraÂcious curiosÂiÂty and intelÂlecÂtuÂal restÂlessÂness. Note how many of the entries are about getÂting an expert to teach him someÂthing, be it mathÂeÂmatÂics, physics or astronÂoÂmy. Also who casuÂalÂly lists “draw Milan” as an ambiÂtion?

LatÂer to-do lists, datÂing around 1510, seemed to focus on Da Vinci’s growÂing fasÂciÂnaÂtion with anatoÂmy. In a noteÂbook filled with beauÂtiÂfulÂly renÂdered drawÂings of bones and visÂcera, he ratÂtles off more tasks that need to get done. Things like get a skull, describe the jaw of a crocÂoÂdile and tongue of a woodÂpeckÂer, assess a corpse using his finÂger as a unit of meaÂsureÂment.
On that same page, he lists what he conÂsidÂers to be imporÂtant qualÂiÂties of an anatomÂiÂcal draughtsÂman. A firm comÂmand of perÂspecÂtive and a knowlÂedge of the inner workÂings of the body are key. So is havÂing a strong stomÂach.
You can see a page of Da Vinci’s noteÂbook above but be warned. Even if you are conÂverÂsant in 16th cenÂtuÂry ItalÂian, Da VinÂci wrote everyÂthing in mirÂror script.
