he received a classical education in Greek and Latin. Jefferson later came to regard the Greek language as the "perfect language" as expressed in its laws and philosophy. While attending the College of William & Mary, he taught himself Italian. Here Jefferson first became familiar with the Anglo-Saxon language, especially as it was associated with English Common law and system of government and studied the language in a linguistic and philosophical capacity. He owned 17 volumes of Anglo-Saxon texts and grammar and later wrote an essay on the Anglo-Saxon language. Jefferson claimed to have taught himself Spanish during his nineteen-day journey to France, using only a grammar guide and a copy of Don Quixote. Linguistics played a significant role in how Jefferson modeled and expressed political and philosophical ideas. He believed that the study of ancient languages was essential in understanding the roots of modern language. He collected and understood a number of American Indian vocabularies and instructed Lewis and Clark to record and collect various Indian languages during their Expedition. When Jefferson moved from Washington after his presidency, he packed 50 Native American vocabulary lists in a chest and transported them on a riverboat back to Monticello along with the rest of his possessions. Somewhere along the journey, a thief stole the heavy chest, thinking it was full of valuables, but its contents were dumped into the James River when the thief discovered it was only filled with papers. Subsequently, 30 years of collecting were lost, with only a few fragments rescued from the muddy banks of the river. Jefferson was not an outstanding orator and preferred to communicate through writing or remain silent if possible. Instead of delivering his State of the Union addresses himself, Jefferson wrote the annual messages and sent a representative to read them aloud in Congress. This started a tradition that continued until 1913 when President Woodrow Wilson (1913–1921) chose to deliver his own State of the Union address. Inventions Jefferson invented many small practical devices and improved contemporary inventions, including a revolving book-stand and a "Great Clock" powered by the gravitational pull on cannonballs. He improved the pedometer, the polygraph (a device for duplicating writing), and the moldboard plow, an idea he never patented and gave to posterity. Jefferson can also be credited as the creator of the swivel chair, the first of which he created and used to write much of the
