Skeletons in a mass grave from 1720–1721 in Martigues, near Marseille in southern France, yielded molecular evidence of the orientalis strain of Yersinia pestis, the organism responsible for bubonic plague. The second pandemic of bubonic plague was active in Europe from 1347, the beginning of the Black Death, until 1750.

The numerator of the upper line is the labor force (i.e., both employed and unemployed), while the numerator of the lower line is the employed only.

Altar of Santa Cecilia in Trastevere, as arranged in 1700. It is one of many churches in Rome whose altar, placed at the western end of the church, was positioned so that the priest necessarily faced east, and so also towards the people, when celebrating Mass. The first Roman churches all had the entrance to the east.[1]

Governor-General Louis Mountbatten's 1947 proposal for the flag of India, effectively the flag of the Congress but with a Union Jack in the canton. It was rejected by Jawaharlal Nehru, on the grounds that he felt that Congress' nationalist members would see the inclusion of the Union Jack as pandering to the British.[27]

ADC squadrons at Thule Site J and Clear AFS used each AN/FPS-50 to sweep 2 radar beams each ~1° in azimuth x 3.5° elevation (illustrated much less thick). Azimuth sweeping created a "Lower Fan" centered at 3.5° elevation and "Upper Fan" at 7° (both illustrated much higher) with "revisit time of 2 sec" for ICBM detection.
English: The Thule J-site BMEWS station's detection arcs of 200°[1] was a missile warning "fence" created by 4 radars' separate arcs: each AN/FPS-50 created 2 arcs (shown) centered at 3.5° and 7° elevation@BMW (exagerated in illustration.) Each arc was created by a smaller radar beam ~1° wide x 3.5° high at a "horizontal sweep rate…fast enough that a missile or satellite cannot pass through…undetected"@BMW (e.g., "Lower Fan" and "Upper Fan") --concerns in 1962 of "ERBM's (Extended Range Ballistic Missiles)" were that missile speeds after burnout would be higher than the initially-deployed Soviet ICBMs@NORAD1958B and prevent the sweeping "fans"(revisit time of 2 sec)@Skolnik from detecting the missiles. A missile within the lower arc (~1.75-5.25° elevation) would be detected at a "Lower Fan Q Point" (black dot) and then by the upper fan (black dot with jagged outline), which allowed the impact area to be estimated from "where the object crossed the two fans and the elapsed time interval between fan crossings"@BMW (displays showed the uncertain impact point as an elliptical area.) The free flight range of the missile outside the atmosphere (burnout to reentry) depends on the flight path angle and on the missile's parametric value of Q calculated from altitude and speed--additional ballistic range within the atmosphere to an estimated burst altitude was determined from computerized look-up tables in the Missile Impact Predictor.@BMW
