Russian botanist Nikolai Vavílov is one of the fathers of the botany of cultivated species. His species collection work established the origin of most of the crops we consume today.
In 1962, almost 20 years after his death, diaries of his travels around the world were published. The Libros del Jata publishing house published a translation into Spanish. In them he dedicates a fun chapter to his experience in Spain. He was struck by the way these last two cereals were harvested with ropes, a way that he saw again in a village in Georgia.
