Rubens here demonstates all of his qualities as a figurative draughtsman.
There was also a related title called Study for the Laocoön Group, which can now be found at the Wallraf Richartz Museum and is loosely dated at 1604-1608. As a general rule, Rubens' drawings have proven very difficult to attribute accurate dates. In a similar way to Sandro Botticelli's drawings, there was simply no documentation available on these study pieces which were never intended to reach the public.
Laocoön Group was produced from black chalk on vergé paper and it is likely that the artwork we find here was produced in the same way. Rubens here continues the inclusion of powerful stomach muscles in a display of beautiful masculinity which most remember Michelangelo for bringing to the artistic table.
