Kunsthistorisches Museum, Vienna

Crowds are walking while others go horse-riding towards Golgotha. To the upper right of the painting, a dense circle of onlookers are already waiting, impatient for the spectacle to come. In their middle two crosses are erected with in between a hole being dug to receive the third cross, from which Christ will hang.
