Query: Maria Reiche's Line to Archaeoastronomy   Maria Reiche devoted her life to the study of the Nazca Lines, the most
famous Peruvian geoglyphs. In fact, she was an archaeoastronomer that proposed
for the Lines some interesting astronomical interpretations. We can appraise
her approach using satellite imagery and a free planetarium software. A
discussion of some geoglyphs is also proposed.
