thirteen bearded men in robes sit and lean around a white‑clothed table in a dim interior. The central figure stands slightly behind the table, raising one hand as he speaks, while the others react with animated gestures and varied expressions, some turning toward him, some arguing among themselves. Plates of bread, a fish, cups of wine, and glass flasks are scattered on the table, with bare feet and legs visible beneath. At the bottom of the scene sit a brass basin, a metal flask, and a small dog curled on the floor near the right corner.

This captivating image showcases the journey of the Sun through the sky during the winter solstice (bottom), equinox (middle), and summer solstice (top) in Bursa, Turkey, between 21 December 2007 and 20 June 2008. Using a fisheye lens, the photographer captured the Sun's positions at regular intervals from sunrise to sunset on three different days, illustrating the changing lengths of day and night throughout the year. The variations in the Sun’s daily path across the sky, its height at midday, and the positions of sunrise and sunset, as well as the length of a day, depend on Earth’s axial tilt relative to its orbit around the Sun. The series was taken from a rooftop in Bursa, where the local terrain adds its own unique touch by occasionally obstructing the horizon. Oriented with north at the top and south at the bottom, this visual diary serves as a stunning representation of the Sun’s path for those residing in mid-northern latitudes.

The background of space is black. Thousands of galaxies appear all across the view. Their shapes and colors vary. Some are various shades of orange, others are white. Most stars appear blue, and are sometimes as large as more distant galaxies that appear next to them. A very bright star is just above and left of center. It has eight bright blue, long diffraction spikes. Between 4 o’clock and 6 o’clock in its spikes are several very bright galaxies. A group of three are in the middle, and two are closer to 4 o’clock. These galaxies are part of the galaxy cluster SMACS 0723, and they are warping the appearances of galaxies seen around them. Long orange arcs appear at left and right toward the center. image credit NASA 2022, public domain

A somber 19th‑century interior scene of a church or chapel where people stand in a quiet line. At the center, an elderly, stooped man in a long beige coat leans on a cane and approaches a priest in white robes, who stands behind a dark wooden railing and reaches out a hand offering ashes. Around them, several women and children in dark, modest clothing watch, including a little girl in a red hooded cape who stands beside a taller woman in a gray dress on the right; both have ashes on their foreheads. The background is filled with wooden paneling and columns, and the floor is patterned with black‑and‑white tiles, giving the painting a subdued, devotional atmosphere. painting, Ash Wednesday by Charles de Groux, 1866, courtesy Stedelijk Museum Wuyts-Van Campen en Baron Caroly (#136776), Lier, Belgium
A densely packed 16th‑century village carnival scene in a town square, shown from above. Dozens of small, brightly dressed figures crowd the muddy open space between brick houses and a large gray church on the right. People eat, drink, play games, dance, wrestle, and parade in costume. In the lower center, a man in colorful clothes rides two large beer barrels, while nearby others cook over a fire and sell food from stalls. At the bottom right, a figure dressed as a mock king in pale blue robes sits on a small wheeled platform surrounded by revelers. Scattered props—buckets, masks, musical instruments, benches, and carts—dot the square, and background streets and buildings are filled with more people watching or joining the festivities, creating a busy, chaotic festival atmosphere. painting The Fight Between Carnival and Lent by Pieter Brueghel the Elder in 1559, courtesy Kunsthistorisches Museum (GG_1016)
