Focus on this artwork and explain the Changes to the composition.
The composition has seen a number of changes, the earliest by Tintoretto himself, to the figures behind the king. What appears now probably represents Tintoretto's initial intention, but in the course of painting he abandoned the two figures standing behind the king, a tall twisting one with a long scarf who was presumably Haman, and what is now a very dim outline of a turbaned companion. Instead Tintoretto overpainted these with a boy in armour. This stage can be seen in a workshop copy in El Escorial, and a print made in 1712 after the Royal Collection painting.  The Escorial version also extends the composition to both sides, and very slightly at the top and bottom, adding one and a half figures at the right, and showing the full leg and foot of the boy with a dog at left.It appears that at this stage the group of rather distant background figures to the right of the king were added; these appear to be Haman and his companion, with similar scarf and turban to their overpainted figures, standing with soldiers carrying banners.At some point after this a restorer removed the boy in armour, probably damaging the turbaned man. The figures revealed were perhaps thought unsatisfactory, so either this or another restorer re-added the boy in armour, though the new figure was "clearly of inferior quality". This stage can be seen in old photographs. In 1950 a proposal by the restorer Sebastian Isepp to remove the new boy in armour was agreed, leaving the figures as they now appear.  Haman is therefore depicted twice in the painting as it now appears.
