Les échecs "courrier"
This Chess variant is one of the most known. It has been played in some places of Germany, especially in Ströbeck, for a rather long period. Having appeared in Middle Age, it has been remarked for its early introduction of a piece moving all along the diagonals, like a forerunner of the modern Bishop.
Another reason for its celebrity is because it makes the center subject of the Dutch painter Lucas van Leyden around 1508.

The board has 12 columns and 8 raws, with checkered colors. The painting shows a white square at players' righ hand, whereas a conserved board at the Ströbeck Chess Museum has a black one. There were probably no firm rule for this point.

Every player has 24 men: 1 King, 1 Queen, 1 Sage or Counsellor (Mann, Ratgeber), 1 Jester or Spy (Schleich), 2 "Couriers" (Kurrier), 2 Archers (Schütze), 2 Knights, 2 Rooks and 12 Pawns.
King: moves 1 step in all 8 directions like the modern King. The King could not make any jump at his first move. Castling was ignored.
Queen: moves 1 step in all 4 diagonal directions. (This very limited moves was that of contemporary mediaeval Chess, before the "revolution" of end of 15th century which created the modern powerful move).
Sage: moves 1 step in all 8 directions, exactly like the King. The difference is that the Sage could be put in "prise".
Jester: moves 1 step in all 4 "orthogonal" directions, i.e. along lines and columns.
Courier: this piece was the real novelty and originality of the game, so much that it gave its name to the game. The Courier was moving all along the empty squares of any of the diagonals, just like the modern Bishop of nowadays Chess.
Archer: the name Germans were giving to their Bishop in Middle Ages. It jumps 2 squares in all 4 diagonal directions, leaping over a piece if the intermediate square is occupied. This was the old move of Arabic Fil and Mediaeval Bishop in regular Chess.
Pawn: moves 1 step ahead if this square is empty, and takes 1 square diagonally ahead, just like its modern Chess counterparts. No rules have been recorded as far as Pawn promotion is concerned. Murray (1913) conjonctured that they made have been identical to the rules in use for Chess in Germany at the time of Selenus (1616): the Pawn had to return to his original square by means of three "joy-leaps" (from 8th row to 6th, 4th and 2nd rows on the same file before it can receive promotion to Queen)
The Pawn initial double step was not allowed. Instead, an "advanced" position was normally used to start the games where 3 particular Pawns (those of Rooks and Queen) where placed 2 steps ahead and where Queen was also placed two steps ahead as illustrated here:
The Courier was really a novelty for German Chess players who were then playing the Bishops with old limited move coming from Shatranj, a diagonal jump at the 2nd square. Naturally, that new piece gave its name to the game. The contemporary players were not used to visualize the diagonals on their length and believed that this so surprising piece was surpassing the Rook in strength.
This special Chess game has a surprising rather long history, mostly confined to Germanic lands.

It seems that the game was not in use anymore for the beginning of the 19c. Lucas van Leyden's painting had a tumultuous history: it was hosted in the Königlihes Museum in Berlin. In 1945, it was sent to safety outside of Berlin on one order from Hitler. General Patton's army found it along with many treasures in a salt mine few months later and the painting was sent to USA, in National Gallery of Art in Washington. In 1948, it has been returned to Germany. It is now in the Staatliche Museen zu Berlin, Preußischer Kulturbesitz Gemäldegalerie.
Several attempt have been made to modernize Courier Chess with modern rules. One has been proposed by FIDE Master Paul V. Byway. A description and some annoted games can be found on this link.
Much before this date, a "Courier-Spiel" was proposed by H. G. Albers from Lüneburg in 1821. It is described on this link.
Another manner of making a new birth for this game was to reconstruct it. This was brightly done by Rick Knowlton who made a replica after a deep study of van Leyden's painting. This replica is available and sold on this wonderful dedicated web site: http://courierchess.com/.

The game painted by Lucas van Leyden can now be pursued up to its end!
