I have amounts of pictures of Mathilde. One of them shows the princess riding a horse - the poor animal doesn't look very happy ... :-)
In the late 1870s, when Emperor Franz Joseph was searching for a bride for his son, crown prince Rudolf went to Dresden to see Mathilde. Archduchess Louise wrote that he didn't chose her, because he recognized that her puppy fat was just the beginning of Mathilde becoming one of Ruben's fat ladies. Yeah, that's mean. :-)
Later Archduke Franz Ferdinand, Rudolf's cousin, was sent to Dresden to see Maria Josepha. He didn't like her. This was the most embarrassing situation for the Austrian court as this has been the second refusal of an archduke to a princess of Saxony. It is said that this is the reason why Archduke Otto was forced to marry Maria Josepha - the beginning of an unhappy married-life for both of them.
