Johann Ernst Hanxleden, also known as Arnos Pathiri, was a German Jesuit priest and missionary, best known for his contributions as a Malayalam and Sanskrit poet, grammarian, lexicographer, and philologist. He was born in Lower Saxony, and whilst studying philosophy met a Jesuit priest. This led to Hanxleden volunteering to become a Jesuit missionary in the Malabar region of India. He travelled overland to India, a journey of 14 months, reaching Gujarat in December 1700. He completed his novitiate in Goa and then went to a Seminary at Sampaloor, Thrissur District, Kerala. He learnt Malayalam and the liturgical Syriac and was ordained as a priest in 1706.
After moving to Palayoor, Hanxleden studied Sanskrit and improved his Malayalam, learning under the tutelage of Namboodiri scholars such as Kunjan and Krishnan from Angamaly and Thekkemadom from Thrissur. From 1707 to 1711, he served as secretary to John Ribeiro, the then Archbishop of Cranganore. It is recorded that he also served as the vicar of the main church in Malabar. Later, he moved to Velur, Thrissur, in 1712 and built the Velur Forane Church. From 1729 onward, he spent his time between Velur, Sampaloor, Palayoor and Pazhuvil and it was at Pazhuvil he suffered a snake bite which resulted in his death on 20 March 1732, at the age of 51. He was buried there but, later, when a memorial was built outside the church, his mortal remains were transferred to it; the memorial also houses a historical museum.
Besides composing the Puthen Pana, Hanxleden created the first Malayalam dictionary, as well as grammar books and other devotional material.
