Tally marks record quantities with simple strokes, making them easy to add as items are counted. A common convention groups strokes in fives: four upright marks are crossed by a fifth, so totals can be read and compared in compact groups. The collection brings together examples of individual counts and rows of marks, along with the related idea of tally sticks. Historically, notched sticks served as physical records of quantities or transactions; the exact methods varied by place and period. Together, these examples connect the basic visual logic of tallying with a form of recordkeeping that predates modern written numerals.
