It was in the house on the Friday Market that the dying printer gathered his family about him. His only son had died in infancy, but his five daughters had all lived to be married, three of them to men associated with him in the printing office. The eldest, Margaret, married Francis Raphelingen, the chief proof-reader and an able linguist; while the second, Martina, married Jean Moretus, the father of a long line, of which the eldest sons bore the same name so that they came to be distinguished by numbers, the first being Jean Moretus I--like a line of kings. This son-in-law was Plantin's business manager. The third daughter aided the mother, who ran a linen business in the frugal way that many Flemish housewives have of helping their husbands. A fourth, Magdalen, when only a child, corrected proofs on the _Biblia Regia_ in five languages, and later married her father's Paris agent. The fifth married a brother of Jean Moretus I, who became a diamond-cutter. Plantin had from a very early date adopted the motto "_Labori et Constantia_," together with the emblem of a hand holding a pair of open compasses, which may be seen over the Friday Market gateway to the museum. This emblem, with the motto entwining it in the form of a scroll, or appearing above, below or across it in a hundred variations, is the mark by which connoisseurs can distinguish the products of the Plantin Press. It must have been constantly in the mind of the great printer himself, for on his deathbed he composed the following French couplet, which expresses and describes his own character better than any epitaph could do: "Un Labeur courageux muni d'humble Constance Resiste à tous assauts par douce Patience."
