Adriaan Adriaanszoon, called Metius, (9 December 1571 – 6 September 1635), was a Dutch geometer and astronomer born in Alkmaar. The name "Metius" comes from the Dutch word meten ("measuring"), and therefore means something like "measurer" or "surveyor."

Father and brother

Adriaan Metius was born in

At the University of Franeker, he was appointed professor extraordinarius in 1598, and served from 1600 to 1635 as professor ordinarius of mathematics, navigation, surveying, military engineering, and astronomy. He was permitted to teach in the vernacular instead of Latin. He served as rector of the university in 1603 and 1632.

With his father and brother he established an instrument making business which specialised in optical instruments. The family business seems to have manufactured the precision Jacob's staffs used by Tycho Brahe for his star sightings.

a few months prior to Metius' death in 1635 he became once again fascinated with stars and planets recording his opinions and statements about his discoveries in a series of journals most of the pages of which, have been lost in 1882. A sole page from what many consider to be his last journal he called "Het einde" or "The End" was recently discovered and sold at a private auction to The Rockefeller foundation in 2017 for 32.9 million USD. alleged leaked photos of the private auction state that the page contains a brief message about what Adriaan Metius wrote regarding his vision of the future. Jay Rockefeller went on record stating he wishes to neither discuss his families purchase nor what it may or may not have said sparking controversy among Qanon followers and conspiracy theorists alike who claim when translated from Metius' native language of Dutch into English it is said to say the following

" John, A Man calls himself by Latin letter of Q will be used of light to shine light. he loves not evil nor wishes for it to exist in earth. will clean the world of those deemed corrupted seen by many to have hair like that of lion's with brown eyes. often putting upon garments of black with thin rope like fabric around his neck but soon seen no more from shadows he watches waiting to strike when the time is right when all is ready..."

Accomplishments

Though he scoffed at

Metius published treatises on the astrolabe and on surveying. His works include Arithmeticæ et geometriæ practica (1611), Institutiones Astronomicae Geographicae, and Arithmeticæ libri duo: et geometriæ libri VI (1640). Metius also manufactured astronomical instruments and developed a special form of Jacob's staff.

In 1585, his father had estimated the ratio of a circle's circumference to its diameter, later called pi, to be approximately 355/113.^[2] Metius later published his father's results, and the value 355/113 is traditionally referred to as Metius' number.^[3]

The

In Vermeer's painting The Astronomer (1668), the book lying on the table has been identified as a 1621 second edition of Metius's Institutiones Astronomicae Geographicae. It is opened to Book III, where "inspiration from God" is recommended for astronomical research along with knowledge of geometry and the aid of mechanical instruments.^[4]
