Identity of the boat depicted in the Taruminosho Sashizu drawing

Item 101 of Box-U(Katakana), “Settsunokuni Taruminosho Sashizu”,dated October 1463

The “Settsunokuni Taruminosho Sashizu” drawing, which was featured in Nos. 26 and 27 in the Stories behind the Hyakugo Archives, was exhibited at the Kyoto Prefectural Library and Archives, in a special exhibition titled “400th Anniversary of Excavation of the Takasegawa River: Takasegawa and Water Transportation in Kyoto”. You may have a question whether it was appropriate to exhibit materials concerning the Kanzakigawa river, a branch of Yodogawa in Osaka, in an exhibition concerning water transportation in Kyoto. We hope that you will understand that these rivers are connected with each other.

While we were preparing for this exhibition, an argument occurred among the staff in charge, as to the identity of the boat depicted in this drawing.

Mr. A insisted that it was a ferry boat, while Mr. B thought that the picture itself was not so decisive. Well, what should we write in the explanation to be placed in the exhibition hall? We were pressed for time, and finally Mr. A’s opinion was adopted, and the explanation was written as “A boat with one oar floats on the river.” But the question was not actually answered.

Let’s look at the rationale for Mr. A’s “ferry boat” theory:

Item 121 of Box-CHI(Katakana),“Nijuikku-kata Hyojo Hikitsuke”, dated 1463

The Toji Hyakugo Archives contain volumes titled “Nijuikku-kata Hyojo Hikitsuke”. They consist of minutes of meetings (“Hyojo”) held by “Nijuikku-kata”, which was an in-house organization of Toji monks. An article dated October 13 in the volume for 1463 (Item 36 of Tenchinobu) mentions Taruminosho. It is written in this article, “渡船のこと治定なり。他領と寺領、毎月15日つつ渡すなり。仍て船賃毎月廿疋なり。只今は入道、取の由、申す者なり。その段、披露しおわんぬ。” This reports that an issue concerning ferry boats has been resolved, where Enoki Keitoku, the Daikan (local magistrate) for Taruminosho, had ferry boats travel to and from Juhachigo on the southern bank of the Kanzakigawa river. The focus of the dispute was the days and fares of the ferry boats. Three years before the above article, when he was asked about ferry boats by Kumon of Toji, a person in charge of distributing land tax from Shoen (manors), Enoki Keitoku answered that there were no ferry boats in the estate of Toji (Item 121 of Box-CHI(Katakana)). Therefore, it is considered that Enoki Keitoku and others started the ferry boat service during this period (*1).

So, ferry boats did travel between Juhachigo and Taruminosho in 1463, when said Sashizu was drawn, and Mr. A’s opinion seems reasonable. Let’s listen to Mr. B, then.

In Taruminosho Sashizu are indicated the names of “乗円祐X (深) (Joen Yushin)” and “乗観祐成 (Jokan Yusei)”, as the persons who prepared this drawing. They were dispatched from Toji for undertaking “Hamami” of Taruminosho. According to “Settsunokuni Taruminosho Hamami Toricho”, Volume 1 (Item 45 of Box-NU(Hiragana)) and “Settsunokuni Taruminosho Hamami Mokuroku”(Item 16 of Box-WA(Hiragana)), “Hamami” signifies an on-site inspection of land.

Therefore, Taruminosho Sashizu is a diagram related to land inspection. The purpose of land inspection in 1463 was to identify increase or decrease in the area, compared to Hamami in 1386. Their primary interest was in farm fields. The Sashizu also mainly indicates the blocks and areas in the estate. In other words, the temples, the shrine, trees as land features, boats as a mode of transportation, and other items were drawn as accessories in the diagram. Next, let’s look at how the boat is drawn. Because a beam is drawn inside the boat, it must have had a certain size. One line is drawn across the boat, indicating not an oar, but a pole, Mr. B insists.

We cannot yet determine whether the picture indicates a ferry boat or not. Let’s listen further to Mr. B’s opinion.

The next point is the direction of the boat depicted. It seems that the boat is headed toward the downstream (right side in the Sashizu, in the west) from the upstream (left side in the Sashizu, in the east). So, it cannot be interpreted that this boat is traveling between Juhachigo (upside in the Sashizu, in the south) and Taruminosho (downside in the Sashizu, in the north). The boat is also positioned not on the river between Taruminosho and the Honshima island, but to the south of Honshima, along the mainstream of “大河 (Taiga, large river)”. Therefore, this boat is presumed to depict a vessel that traveled in the large river upstream and downstream. Although activities by Enoki Keitoku as the Daikan were worth attention, it is difficult to consider that the influence of his activities went as far as affecting the Ezu (pictorial diagram), Mr. B asserts. This explanation is rather complicated, but convincing to a certain degree.

What is your determination? Do you support Mr. A, Mr. B, or still another view? Ezus are exciting materials that can be interpreted in many different ways.
