In 1781, Immanuel Kant published the Critique of Pure Reason, one of the most influential works in the history of the philosophy of space and time. He describes time as an a priori notion that, together with other a priori notions such as space, allows us to comprehend sense experience. Kant denies that either space or time are substance, entities in themselves, or learned by experience; he holds, rather, that both are elements of a systematic framework we use to structure our experience. Spatial measurements are used to quantify how far apart objects are, and temporal measurements are used to quantitatively compare the interval between (or duration of) events. Although space and time are held to be transcendentally ideal in this sense, they are also empirically realthat is, not mere illusions.
When did Kant publish one of the most influential works in the history of the philosophy of space and time.

During this period the practice of manuscript illumination gradually passed from monasteries to lay workshops, so that according to Janetta Benton "by 1300 most monks bought their books in shops", and the book of hours developed as a form of devotional book for lay-people. Metalwork continued to be the most prestigious form of art, with Limoges enamel a popular and relatively affordable option for objects such as reliquaries and crosses. In Italy the innovations of Cimabue and Duccio, followed by the Trecento master Giotto (d. 1337), greatly increased the sophistication and status of panel painting and fresco. Increasing prosperity during the 12th century resulted in greater production of secular art; many carved ivory objects such as gaming-pieces, combs, and small religious figures have survived.
When did Giotto die?
A: 1337

Rachel Cain, co-founder of an influential Trax Records, was previously involved in the burgeoning punk scene and cites industrial and post-punk record store Wax Trax! Records as an important connection between the ever-changing underground sounds of Chicago. As most proto-house DJs were primarily stuck to playing their conventional ensemble of dance records, Frankie Knuckles and Ron Hardy, two influential pioneers of house music, were known for their out-of-bounds behavior. The former, credited as "the Godfather of House," worked primarily with early disco music with a hint of new and different music (whether it was post-punk or post-disco) but still enjoying a variety of music, while the latter produced unconventional DIY mixtapes which he later played straight-on in the music club Muzic Box, boiling with raw energy. Marshall Jefferson, who would later appear with the Chicago house classic "Move Your Body (The House-Music Anthem)," (originally released on Chicago-based Trax Records) got involved in house music after hearing Ron Hardy's music in Muzic Box.
