Linked below is a website containing information on Ann Radcliffe's Gothic heroines.

For those who may not have had the opportunity to read The Mysteries of Udolpho yet, here is Radcliffe's description of the heroine:

[Emily's room] contained her books, her drawings , her musical instruments, with some favourite birds and plants. Here she usually excercised herself in the elegant arts, cultivated only because they were congenial to her taste, and in which the native genius, assisted by the instructions of Monsieur and Madame St Aubert, made her an early proficient.

[...]

In person, Emily resembled her mother; having the same elegant symmetry of form, the same delicacy of features, and the same blue eyes, full of tender sweetness. But lovely as was her person, it was the varied expression of her countenance, as conversation awakened the nicer emotions of her mind, that threw such a captivating grace around her.

As Reeba already pointed out, Emily's father takes great pains to insure she receives a proper and thorough education.

St Aubert [Emily's father] cultivated [Emily's] understanding with the most scrupulous care. He gave her a general view of the sciences, and an exact acquaintance with every part of elegant literature. He taught her Latin and English, chiefly that she might understand the sublimity of their best poets. She discovered in her early years a taste for works of genius; and it was St Aubert's principle, as well as his inclination, to promote every innocent means of happiness (Vol. I Ch. I).
