Art is never finished, only abandoned. - Leonardo da Vinci

"Study without desire spoils the memory, and it retains nothing that it takes in."

"As a well-spent day brings happy sleep, so a life well spent brings happy death."

"Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return."

"Truth at last cannot be hidden. Dissimulation is of no avail. Dissimulation is to no purpose before so great a judge. Falsehood puts on a mask. Nothing is hidden under the sun."

"A beautiful body perishes, but a work of art dies not."
