Hadewijch of Antwerp can be defined as a new woman, free and rebellious, with a revolutionary spirituality, pure and intense. A writer of the late Middle Ages of which little is known even today, ignored for almost five centuries, but it is thanks to her that prose and mysticism make their first entry into Dutch spiritual literature. A daring woman who, together with her fellow beguines, fought for emancipation, claimed and conquered a role in society and a totally free love for God, made of desire and passion without being temptation. Hadewijch is not at all a minor writer: she is modern, witty, passionate, she has an immense feeling for God, that nobody has been able to express with such strength and poetry at the same time. Her mysticism is current, made of ups and downs like everyday life. The letters become the privileged tool to probe the soul and invite the reader to do the same. The visions transmit with immediacy and spontaneity his message of Love, still appreciable today.
