I found this postcard by chance. It's dated 1953, the year I was born. It describes Abano Terme (until 1924 Abano bagni). The baths were known to the Romans. Nearby there was an important place of worship and an oracle. The postcard (coloured) reproduces a print of 1761 and comes from the book of abbot Domenico Vandelli (1691-1754), Tractatus de Thermis agri Patavini. Padua, Conzatti, 1761 (in Latin - a letter is inserted at the end, a dissertation dedicated to Linnaeus). On the left, you can see a group of people taking baths in hot water and they are completely naked. Vandelli was also a cartographer and invented the "contour lines" in cartography, so useful to all hikers. He designed the "Via Vandelli" that connects Modena to Massa (Tyrrhenian Sea), which is now a beautiful nature trail through the Apennines (https://en.wikipedia.org/wiki/Via_Vandelli).
