The last hatching method was developed by Charles Segoing, a French heraldist and royal historian in 1654 ("Armorial universel, contenant les armes des principales maisons de l'Europe". Paris, 1654). His system is similar to the method of Petra Sancta. On the table X of his work, Otto Titan von Hefner published still another system of hatching from 1639, attributed to Lobkowitz. (On page 49, footnote 4 Hefner names his source as Rietstap's Handboek der Wapenkunde, p. 96.) His book titled "Philippus Prudens" contains as many as 27 engraved portraits of the Portuguese kings, among them several with hatched coat of arms, but there is no hatching table at all. However, in his earlier book from 1636 we can really find a hatching table. (One of the book censors was Christophe Butkens.)
