"I distinguished the light sleigh drawn by a chestnut courser"

The image of Nabokov's mother wearing her seal furs in her sleigh in wintry St Petersburg streets is one of the most evocative ones of Speak, Memory and it certainly sums up the style in which the Nabokovs lived in Russia. Seeing as it was drawn by a single horse, the sleigh may have been one like this, although Nabokov describes the coachman as being in front of the rider.
