George von Rheticus[2] was a wizard astronomer. He had portraits of himself hung at Hogwarts Castle.


1995–1996 school year

By the start of the 1995–1996 school year, his portrait hid a secret passage between the Grand Staircase and the seventh-floor corridor. His password was "Scurrilous Scoundrel." When Hannah Abbott asked for a shortcut to somewhere near the Room of Requirement so she was not caught by Dolores Umbridge, Harry Potter told her about this portrait.[1] There was another portrait of him hung at the Viaduct Entrance, hiding a shortcut to the Grand Staircase. The latter's password was "Iunctis viribus."[3] He had yet one more portrait next to the Second-floor girls' lavatory, near the Tapestry Corridor. Not hiding any shortcut, this portrait knew about the current events at Hogwarts School and liked to help students keeping out of trouble, if they proved to him they weren't "scoundrels," that is.[3]

1996–1997 school year

The following school year, 1996-1997, von Rheticus's portrait had been moved to the Entrance Hall, this time hiding a way to the Portrait Room.[2]

Personality and traits

This portrait was very helpful and did not mind helping Hogwarts students when they needed it. He once helped Harry Potter finding a broken suit of armour in order to avoid punishment from Severus Snape.[3] He also gave his password to Harry Potter in order to help fellow Dumbledore's Army member, Hannah Abbott.[1] However her refuses helping people whom he suspects are, as he put it, scoundrels. In his view, no scoundrel is good at Astronomy, so when he thinks someone is one, he asks him to fill in a star chart in order to know if they are trustworthy.[3]

Behind the scenes


The name "George" comes from the Greek name Γεωργιος (Georgios) which was derived from the Greek word γεωργος (georgos) meaning "farmer, earthworker", itself derived from the elements γη (ge) "earth" and εργον (ergon) "work". Saint George was a 3rd-century Roman soldier from Palestine who was martyred during the persecutions of emperor Diocletian. Later legends describe his defeat of a dragon, with which he was often depicted in medieval art.
