This was painted in the early 1900s – a date of 1904 is sometimes quoted but that is just the latest possible date, it may have been completed earlier. There are similarities to Illusions – the armour, the chain mail, the red drape over the left arm.
The painting is known today as ‘Joan of Arc.’ The Illustrated London News, 23 April 1904, mentions a picture by Annie on display at the New Gallery called ‘Faith,’ “with the strong expression of the face – an expression without the aid of eyes, for they are closed – might also be a Joan of Arc; the head is thrown back, in intense meditation, and the hands rest on the cross of a sword.” Similar comments referring to a picture called ‘Faith’ are made in the Whitchapel Gallery Spring Exhibition catalogue, 1907. I have assumed they both refer to this painting, hence the title used here.
Below is the image with the colours adjusted to try to remove age-related browning.
