Anider is the principal river associated with Amaurot, the centrally situated chief city of Utopia. In Raphael Hythloday’s account, it shapes the city’s position, connects its streets to maritime traffic, and forms one side of its defenses. The river is not merely scenery: its changing waters and carefully protected sources are woven into the practical organization of urban life.

Course and Setting

Anider rises in a small spring about eighty miles above Amaurot. Fed by other streams, including two of notable size, it has widened to about half a mile by the time it passes the city. It continues to grow broader downstream and reaches the ocean after a further sixty miles. Amaurot stands beside it on rising ground, with the river running along the lower side of the city.

The account distinguishes the river’s changing character along this course. Between Amaurot and the sea, and for some distance upstream from the city, Anider is affected by a powerful tide that turns every six hours. The incoming tide carries salt water roughly thirty miles inland; farther upstream the water is brackish, while at Amaurot it is fresh. When the tide ebbs, the river remains fresh all the way to the sea.

Crossing and Maritime Access

A substantial bridge crosses Anider at the side of Amaurot farthest from the sea. Built of stone rather than timber and formed from many arches, it provides a durable crossing without obstructing vessels: ships can lie along the town’s riverbank. The placement thus accommodates both movement across the river and access by water, linking the city’s land routes with its river traffic.

Anider’s position also suits Amaurot’s civic role. The city is Utopia’s principal gathering place, where representatives from the other cities meet to consult on common affairs. Its river frontage and bridge belong to the practical setting of that central city, rather than being presented as an isolated geographical curiosity.

Water Supply and Defense

A smaller river rises on the hill where Amaurot stands, flows through the city, and joins Anider. Because its spring lies just outside the walls, the inhabitants have fortified its source so that an enemy besieging the city cannot stop or divert the flow, or poison it. From there, water is carried in earthen pipes to the lower streets. Where those pipes cannot supply it, large cisterns collect rainwater as a reserve.

The city’s defenses likewise incorporate its waterways. Anider serves as a natural ditch along one side of Amaurot; a broad, deep, thorn-planted dry ditch protects the other three sides, while the town is enclosed by a high, thick wall with towers and forts. The river therefore contributes to a defensive boundary, while the protected spring and cisterns address the distinct vulnerability of maintaining water during a siege.

Place in the Account

Raphael’s description gives Anider several connected functions: it marks the terrain on which Amaurot is built, carries tidal and freshwater conditions to the edge of the city, permits ships to berth beside it, and helps define the city’s defenses. The attention to the separate stream, its guarded source, and the rainwater cisterns makes water security as concrete a part of the account as the bridge and the river’s course. Anider is presented as an element of an organized urban environment, where access, supply, and protection are considered together.
